A circuit breaker is an electrical switch that protects circuits from two types of damage: damage due to overload, in which a greater than requisite supply of electricity travels through a circuit; and damage due to short circuit, in which an electrical current travels along a path of low electrical impedance. When breakers sense these conditions, they automatically disconnect the flow of electricity to a circuit. Fuses serve the same function. But, unlike breakers, they cannot be reset and must be replaced after interrupting a current.
The importance of Testing and the Types of Tests Performed
High Voltage Power Supply Surplus
Breaker testing centers on the prevention of two things: electrical fires and irreparable damage to costly equipment due to overload and short circuit. As one would expect, testing on a domestic level differs significantly from testing on a commercial/industrial level, with the latter requiring more than one type of method. More often than not, tests are performed as a part of routine maintenance, using one or more of the following methods to locate early problems: dynamic taste resistance measurement, arcing taste inspection, vibration analysis, and abnormal end of trip impact inspection.
1. Dynamic taste Resistance Measurement
Conducted at a variety of current speeds (usually at 100 A and above), dynamic taste resistance estimation measures the resistance of a breaker to addition electrical stimulation, and is typically used to test breakers with Sf6 insulation.
2. Arcing taste Inspection
Arcing taste inspection has two aspects: ensuring the proper alignment of arcing contacts, the misalignment of which can consequent in uneven wear to the arcing contact; and ensuring that the tungsten tips of arcing contacts remain properly attached. In some instances, the old can be carefully through dynamic taste resistance measurement, while the latter typically requires by hand inspection.
3. Vibration Analysis
Vibration diagnosis is performed using special software that detects vibrations resulting from developing mechanical problems in high voltage breakers, normally of the Sf6 type.
4. Abnormal End of trip Impact Inspection
Abnormal end of impact inspection focuses on detecting the occurrence of abnormal electrical impact on keep insulators or other parts. Detecting the abnormal impact can prevent the exchange of costly parts.
Breaker Maintenance and exchange Switch Maintenance in One service Agreement
Maintaining breakers is a requisite service than many entities outsource to a professional power supply service that specializes in commercial and commercial power solutions, and one that is often packaged with exchange switch servicing, a service requisite to the function of backup generators. To find out what type of tests are best for your company's breakers and to learn either its backup generator's exchange switch is ready for the next power outage, taste a power supply service that specializes in maintenance, consultation, and the supply of power equipment.
