Megger Group Ltd.
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.

EUROSMC, S.A.
Before developing the system or equipment for the testing of a circuit break timer for distribution, the application information was obtained by consulting various users of this type of timer for circuit breaker. The customers consulted were from private service and maintenance companies, large industries, and of course from the Utility companies. It is essential to receive first hand information of the actual requirements and needs of each of these customers who are making these types of tests and then make a detailed study of the various alternatives offered by different manufactures of this type of circuit breaker timer.

Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.

SCR ELEKTRONIKS
The test system is designed and customized to carry out 2.55*Intest as per Table 7 (test c) of IEC 60898 (also mentioned for routine testing of MCBs. The test is done at dc current to exactly analyze and correct the bimetallic properties of the MCB as far as thermal tripping is concerned. The unit comes with a pneumatically operated test fixture with in-built dc stepper motor that is controlled by a micro controller / PC to calibrate the breaker into a narrow tripping band programmed by the user.

EUROSMC, S.A.
It allows to perform with sufficient power, all the primary current injections to test the proper function and wiring of all the elements that compose the protection and measuring section in a substation.The regulation system is based on a continuously variable autotransformer (Variac) that supplies to a power transformer that delivers the high current outputs and isolate the main supply from the load. A built-in ammeter and a timer gives the information about the current value and the operation time of the relay or breaker under test.
