Testing of instrument transformers

 

Instrument transformers play a critical role in ensuring the accuracy and reliability of power systems. For both measurement and protection purposes, it is essential to regularly test and calibrate these transformers. Current (CTs) or voltage (VTs) instrument transformers must maintain a high degree of accuracy to ensure correct billing, while circuit breakers must operate accurately and quickly to provide the highest level of safety. Regular inspections of these instrument transformers ensure that they function as intended, providing reliable and accurate measurements as well as protection in the event of a fault. Ensuring the proper functioning of these instrument transformers is essential to maintaining the continuity of power systems and should be a top priority for every power utility.

What exactly is circuit breaker testing?

 

Testing circuit breakers is a critical step in ensuring the safety and reliability of electrical power systems. Essentially, circuit breakers are devices that interrupt the flow of current within a circuit in the event of an overcurrent.
Testing these devices is intended to ensure that they function properly, both under normal operating conditions and under fault conditions such as a short circuit. Circuit breaker testing involves a series of comprehensive checks of the devices and their components, including thermal and magnetic tripping tests. Regular maintenance and testing of circuit breakers are essential to minimize the risk of failures and malfunctions and to ensure power continuity in critical facilities.
