How to Analyze a High Voltage Transformer

Generally, Transformers convert voltage for make use of in appliances. High-voltage or "step-up" transformers twist lower voltages into higher voltages. A high voltage transformer is a type of electrical transformer. An appliance similar to microwaves utilizes high-voltage transformers. As they cause a risk of shock, the transformer must be detached, and the capacitors bled, prior to testing. With a willingly accessible resistance tester, however, the whole procedure becomes trouble-free, fast and extremely informative. Knowing how the transformer functions helps identify what the outcome of the tests mean. It will resolve either the transformer itself is faulty, or if it is operating appropriately.

Instructions:

1. Isolate the transformer from its power supply.

2. Consent to power to exhaust from the capacitors. If the division utilizes high-voltage capacitors without exhaust resistors, it may be critical to short-circuit the capacitors. If not, just agree to the resistors to consume power from the capacitors on their individual.

3. Check that the component has no control with the voltmeter.

4. Cut off the high-voltage transformer guide from its valve on the transformer suitable. This may engage just unplugging the wire, or it may need that a set screw be detached. If there are some high-voltage valves, Isolate each of them now.

5. Place the ohmmeter to its most responsive. Pathology for resistance among the final just detached and the earth. The indicator should exhibit anywhere connecting about fifty to about seventy ohms (50-70 O) of resistance stuck in the middle of these two points. critical variance from this series indicates an imperfect transformer.

6. Divide the guide to the key in terminals on the transformer, subsequent to the similar method as for the high-voltage outputs.

7. Check with the ohmmeter connecting each input terminal. The meter should gift a very low down reading (close up to zero ohms (0 O)) among these terminals. Also a great deal resistance stuck in the middle of these terminals specifies a fault in the transformer.

8. Test in the middle of all of the input terminals and the ground. The ohmmeter be supposed to account for infinite ohms (8 O), representing no relationship at all in the middle of these points. Some finite resistance here designates a short circuit.

9. Isolate the low-voltage productivity escorts, and test for resistance in the middle of those workstations. The ohmmeter should show a low, finite evaluation (less than one O), as with the key in terminals. In excess of resistance there shows a mystery with the transformer.

10. At last, test in the middle of the low-voltage productivity terminals and the position. The measuring gadget should demonstrate infinite ohms (8 O), signifying no relationship at all. Once again, any link here specifies a short circuit.

11. If the whole resistance readings appear proper, clean off the workstations and reconnect the guide, then reconnect the transformer. The Pathology indicates that any troubles with the law lie down elsewhere.

Jvc Vcr Problems In Model Hr-J321Em-No Power

A buyer sent me a Jvc Hr-J312Em model Vcr for repair. The complaint was no power. I personally don't heal Vcr because I'm more on computer monitor repair. Because of he is a friend of mine; I told him that I'm willing to take the challenge to heal it. Repairing Vcr at my era categorically has begun to go obsolete because of the shop filled with Vcd players. Vcd player is cheaper than Vcr and contract in term of the size. Back then, many habitancy sent their contract disc and laser disc players to electronic heal shop to turn the players into Vcd player.

What the technicians do was to add in a mpeg or Vcd card and tapped the Efm Rf signal from the Dsp ic. When you buy the Vcd card, it came along with a list of the Dsp ic part numbers and pin out and shown you at where you suppose to tap the signal. It was a 15- 20 minutes job and you could earn a lot from it. But now, everyone is using Dvd player and Vcd already obsolete.

Come back to the Vcr player, after opened up the casing and placed my probe on the two pins of the main filter capacitor, I could see the capacitor still holding the charge. If the voltage present at the capacitor pins, this tells us that the main ac voltage is coming in, the fuse and the bridge rectifier is working. There must be a surmise as to why the main filter capacitor still holding the charge. By following the inescapable marking pin of the main filter capacitor, I traced the line circuit and saw two high ohms resistors connected in series.

These two resistors are called start up resistors. The function of the start up resistors is to sacrifice the dc voltage to a lower value where it can then be supplied to the oscillator circuit and switch the power fet. If either one of the start up resistor developed an open circuit, there would be no supply voltage to the oscillator circuit and the power fet would not switch. Therefore no ac voltage produced at the secondary side of the power supply.

For the above Vcr, I found a start up resistor (220 kilo ohms) open circuit and causing no power symptom. Other components such as the power fet, filter capacitor and diodes found to be in good condition. For your information, if either one of the start up resistor spoilt, you have to replace both otherwise the other one would come to be defective after in assistance for sometime. Replacements of the two resistors brought the Vcr back to life again.

Conclusion, either you are repairing the Jvc Hr-J312Em model Vcr or any kind of electronic equipment, if you came across the main filter capacitor still holding the charge even with power off, surmise a defective start up resistors. However, inescapable electronic tool power supply designed, the capacitor may still hold charge even the start up resistors seems to be working. In this case you have to use other troubleshooting techniques to solve it. Please refer back to my website for more electronic troubleshooting tips.

electric Radio Controlled Boats Motors - Brushed Vs Brushless

The two types of galvanic motors currently being used in the radio controlled boats hobby are the brushed motor and the brushless motor.

What are they, and which one is best? Good Questions...let's take a quick look at these two types of galvanic motors.

To begin, all galvanic motors have magnets and coils of wire (windings). You don't have to remember any of your high-school physics, but the basics are that a coil of wire intriguing in a magnetic field creates an galvanic current. When you have a varying current through a coil of wire it will move relative to the magnetic field...in other words, it goes round and round!

• First is the brushed motor

Most galvanic radio controlled boats use a brushed motor. These brushed motors look somewhat like a small metal can with an axle sticking out of one end and battery leads on the other. Inside that 'can' are the commutator shaft, the armature, wires, carbon brushes, and magnets.

The carbon brushes press against a spinning commutator (a set of electrical contacts on the armature) causing friction. This caress forms an electrical circuit between the Dc electrical source (battery) and the armature coil-windings. When voltage is applied through the battery leads to these brushes it causes the motor to spin and gives transmit and reverse motion to the radio controlled boat.

The downside of this configuration is the positive conflict puts extra strain on the motor, and the brushes wear down with use...therefore needing periodical replacement.

In addition, the windings are pretty heavy to rotate, and since they are in the middle of all things they have strangeness getting rid of waste heat being created. Not only that, but the brushes make imperfect caress with the commutator as currents and speeds increase. So, you can see that there are quite a few losses in this setup. In institution a brushed motor will rarely be more than about 65-70% efficient.

• Now let's eye the brushless motor

The brushless motor is becoming increasingly popular in the radio controlled boats hobby. Why is that? Well, one of the appeals of a brushless motor is in the sheer power it can give to your galvanic radio controlled boat. Brushless motors, as you might guess, do not have brushes. In turn, they don't wish frequent cleaning, and without the brushes there is less conflict which results in less heat -- the biggest killer of motor performance.

Another intriguing factor for brushless motors is that they can cope a much higher voltage than brushed motors. With an increased voltage supply, brushless motors can in effect help man new to radio controlled boating race at blistering speeds!

How does the brushless motor work? In divergence to its 'brushed' counterpart, the brushless motor has a permanent magnet in the rotor or shaft. There are sensors that decree the direction and how fast the magnet turns in order to yield voltage. Unlike the carbon brushes of the brushed motor, these sensors do not touch the armature.

In this configuration, the permanent magnets rotate and the armature remains static...opposite of the brushed motor model. This eliminates the question of how to replacement current to a intriguing armature. In this setup, the brush-system/commutator assembly is replaced by an electronic controller. This controller performs the same power distribution function you will find in a brushed motor, but instead uses a solid-state circuit instead of a commutator/brush system.

This setup eliminates friction, and therefore results in much greater efficiency and a huge increase in power - a brushless motor can be up to 300% more great than a brushed motor. Plus, gone is the issue of brush replacement!

There are assuredly advantages to running with a brushless motors...the first one being the brushless motor requires less maintenance and can be more reliable. A brushless motor can, in most cases, supply more torque and more efficient power than a comparable brushed motor.

Even though the preliminary cost of a brushless system is higher, if you factor in the maintenance and other costs connected with a low turn, great brushed motor, the cost will very speedily interpret itself.

Keep in mind, however, these motors are only just now becoming legal in some professional radio controlled racing circuits! That may or may not apply to your private situation and/or needs.

So, there you have it. The decision is yours...brushed or brushless. Think your private needs and goals, as well as cost and choose from the many radio controlled boats the one that is right for you right now. The thing is, your skills and goals will change over time, and you can in effect have more than one boat...one for every occassion!!

Get out there and have Fun!!

Defibrillators - An overview

How do defibrillators work?

A defibrillator is a healing gismo used to accurate irregular heart beat patterns, otherwise known as cardiac arrhythmias. Cardiac arrhythmias are caused by abnormal electrical activity in the heart, characterized by irregular contractions. Many arrhythmias are often common and benign, most often described as feeling your heart skip a beat. Other arrhythmias, however, can interrupt the general flow of blood, causing vital organs such as the brain to lose oxygen and suffocate. If left untreated, these arrhythmias can be deadly in very short periods of time. Defibrillators are most commonly used to treat two very hazardous types of arrhythmias: ventricular fibrillation, or 'V-fiB,' and ventricular tachycardia, or 'V-tach.'

Today, defibrillators can be movable units located in ambulances, automated units located in a group area, or even an implantable unit located directly into a patient's body. No matter the style of defibrillator, the medicine remains the same. Applying a quick, high-voltage, direct-current fee to the patient's chest, allows a defibrillator to disrupt abnormal rhythms and prompt the heart to resume its general rhythm. Despite the power of the shock that a defibrillator supplies, technological advances have created lower-energy shocks which are much less likely to cause internal damage and burns.

What are the risks connected with using a defibrillator?

Although defibrillators can save lives, defectively designed defibrillators can cause a great deal of damage and even lead to death. Studies show that defective Sprint Fidelis leads in Medtronic's implantable defibrillator are prone to fracture, causing the units to issue qualified shocks at random. These shocks may cause intense pain, anxiety, and even death for people with implanted units.

If you or a loved one has been implanted with a Medtronic defibrillator with Sprint Fidelis leads, taste an attorney immediately to discuss your legal options. A skilled attorney will be able to evaluate your case and contribute you with the legal aid you need to navigate the involved litigation process. The outcomes of using a defective Medtronic defibrillator may cause you to struggle financially, emotionally, and physically. There is no theorize to face the hardships connected with defective products when your situation was caused by a poorly man-made or defective product. Manufacturers are often found liable for injuries caused by their products and an experienced attorney will be able to help you manufacture the most productive lawsuit possible.

High Voltage Power furnish - An overview

A high voltage power furnish is designed to output high voltage energy. The features that are included in the unit will vary from builder to builder and from model to model. Some units are designed for single uses. Among those uses are lasers, x-rays, other healing equipment, semiconductors, commercial application, and a whole of other uses.

There are a whole of different features that you will commonly find in a high voltage power supply. Among these features are the sort of energy input that is compatible with the unit, either the unit is programmable, and the range of output that the unit can provide.

If you think of the unit in the terms of a cylinder you can beyond doubt photo the process that is involved. Some form of energy or potential energy is settled into one end of the cylinder. Within that cylinder the energy is changed and the voltage is regulated at a high rate. The energy then passes out the other end in the designated condition. This is the process involved in all high voltage power furnish units.

For the first step in the process, input, there are a whole of basic options. Among the most common are electric energy. This can be input in either Ac or Dc form depending on the unit that you are working with. In expanding to approved electricity plugs batteries are also used. These may range from small batteries for some units to large batteries in other cases. Batteries are especially beneficial when the intention is to allege a constant energy supply. Batteries are also used in conjunction with electric input from a plug for example. In this way there is a backup in the event that the traditional power input is interrupted. Beyond batteries there are alternate fuel sources. These may be in the form of gasoline or other fuels that can somehow be converted into electric energy. The specialized units that perform this function are often called generators. Some models of generators may furnish low voltage power instead of high voltage. In some cases solar panels can also be used. These furnish electric energy that is converted from light. There are also a range Usb input that is now being used for definite high voltage supplies. These and other innovations characterize a new horizon in power supply.

Depending on the specifications of the single high voltage power furnish unit something is done inside the furnish unit. Often with high voltage supplies the ensue is that the voltage of the energy introduced is increased significantly. There is a inevitable whole of control over the output in many of these units. While some units are designed to only output at a single energy rating some allow the user to take discrete outputs. In some cases these extra units are referred to as selectable output or programmable units. With a classic programmable unit though there is often some whole of computer control over the output. In some cases software can allow a computer to beyond doubt program the unit. It may also allow for monitoring of the output via computer. output selectivity can consist of choice of a single voltage range and even choice of alternating or direct current in some models.
