  • Primary injection is the test method that allows the user to verify the functionality of a low voltage circuit breaker and its component with certainty. Using this technique, the main contacts, operating mechanism, de-ion chamber, trip unit and terminal connectors are tested. The traditional instruments required to perform this test have to deal with manual output current adjustment, current decay, and dc offset phenomena. The new generation of primary injection testers will help overcome these situations in the field with both new hardware and software capabilities. Join this webinar to learn about modern primary injection features and step-by-step procedures for the basic measurements using Megger's Smart Primary Injection test set, SPI225, the latest addition to the Megger family of primary injection instruments.
