What kind of high voltage tester should I opt for? It is recommended to have a Portable High Voltage Tester so that it can be easily transported to multiple places and complete maintenance on the high voltage equipment. Not only can it determine the faults in the system, it can also extend the lifespan of the equipment under test. Skipper high voltage tester comes with features such as compact size, longer duty cycles, automatic tripping, safety and zero start interlock to ensure safety of the operator and the equipment alike. Why to use Primary Injection Kit (PIK)? When it comes to testing of electrical systems, one of the most important test is the primary injection test. It is broadly used for two applications - 1. Testing of protection systems with elements such as circuit breakers and relays in them. 2. Testing of a current transformer in protection systems. In high current/high voltage situations encountered in massive electrical systems such as substations or power stations, primary current injection test kit can be used. A strong current (depending on on equipment configurations and test requirements. For example, our Primary Injection Kit PIK2000 injects 2000 Amperes) is pumped directly into the primary side of an electrical circuit such as a circuit breaker/current transformer. Primary injection testing is appropriate for over-current trip relays connected to a circuit breaker, to determine the ratio of current transformers. Because of the timer present in our Primary Injection Kit, relays can be tested to their full extent of operation times. The aim of the test is to determine how the system performs under different degrees of current load. Through inserting current into the device, we could determine whether the breaker will trip or fail, as well as how long the current will reside until the circuit is broken. Aside from these safety device implementations, current injection test sets are suitable for just about any system where a low resistance load must be supplied with a regulated and tested strong current. When to use Primary Current Injection Kit? Primary Injection Kit is usually used after major repairs or for regular routine check-ups. It is also used during the establishment and installation of the applications mentioned before.
