Stationary and mobile Instrument Transformer Test Systems (ITTS) are used for testing current (CT) and voltage (VT) transformers. Possible test are e. g. accuracy test, demagnetisation and insulation test.
The primary testing includes constant current sources for testing circuit breakers, compact circuit breakers or motor circuit breakers (equipped with thermal and/or magnetic releases).
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 have a high level of accuracy to ensure proper 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 are functioning as intended and providing reliable and accurate measurements, as well as protection in the case of a malfunction. Ensuring the proper functionality of these instrument transformers is essential to maintaining the continuity of power systems and should be a top priority for any utility.

What exactly is switchgear testing?
Circuit breaker testing 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.
The purpose of testing these devices is 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 on the devices and their components, via thermal or magnetic trip testing. Regular maintenance and testing of switchgear are essential to minimize the risk of failures and faults and to ensure continuity of power supply in critical facilities.

Low voltage switchgear testing
The testing of low-voltage circuit breakers is an important aspect of ensuring the safety and efficient operation of electrical systems. This testing involves a series of measurements on breakers to identify any faults or inefficiencies that may exist. Regular testing can correct potential problems before they lead to system failures, saving both time and money in the long-term. It's important to assign this important task to experienced professionals who understand the intricacies of low-voltage circuit breakers. Knowing that your system has been thoroughly tested and is functioning optimally is invaluable.
