circuit breaker is an electrical switch that protects the circuitry of two types of damage: damage due to overloading, which is more than the required supply of electricity travels through the circuit and damage due to short circuit, in which electricity travels the path of low electrical impedance. When switches the meaning of these conditions, they automatically turn off the flow of electricity to the circle. Fuses serve the same function. However, unlike switches, they can not return and must be replaced after a power interruption.
The importance of tests and types of tests
Breaker testing center to prevent two things: electrical fires and irreparable damage to expensive equipment due to overloading and short circuits. As one would expect, the test on the local level varies considerably from testing on a commercial / industrial level, the other requiring more than one type of method. More often than not, the tests are performed as part of routine maintenance, using one or more of the following methods for early detection of problems:. Dynamic contact resistance measurement, arcing contact inspection, vibration analysis, and abnormal end of travel impact of inspections
1 Dynamic contact resistance measurement
conducted at various current speeds (typically at 100 and higher), the dynamic contact resistance measurement measures the resistance to increase battery electrical stimulation, and is commonly used to test circuit breakers with SF6 insulation.
2 Contact Sparks inspection
arcing contact inspection has two aspects: to ensure proper alignment arcing contacts, a move that could lead to uneven wear on the contact arcing and ensure that advice tungsten arcing contacts remain plugged. In some cases, the former can be determined by measuring the dynamic contact resistance, while others typically require manual review.
3 Vibration analysis
vibration analysis is done using special software that detects vibrations arising from the development of mechanical problems in high voltage circuit breakers, typically SF6 type.
4 Abnormal End travel impacts inspection
Abnormal end of the impact of inspection focuses on the detection of abnormal electrical phenomena effects on the support insulators and other parts. Detecting abnormal performance can prevent costly replacement parts.
Breaker Switch maintenance and transfer of maintenance in a Service Agreement
Maintenance switch is a critical service to many companies outsource supply professional service that specializes in commercial and industrial strength solutions, and one that is often packaged with the transfer switch service, service is critical to the function of backup generators. To find out what kind of tests are best for your company's switches and to learn whether a backup generator transfer switch is ready for the next power outage, contact your service power that is specialized in maintenance, consulting and supply of power equipment supply.
