MEGGER SPI225-SMART PRIMARY INJECTION TEST SYSTEM

The megger SPI225 is a high-current primary injection test system for all forms of high-current testing required in a substation, including testing overcurrent relays, circuit breakers, motor overloads, and current transformers.

The SPI system is the FIRST high-current test system to permit a user to type in a predetermined current and the SPI system will generate and regulate the requested high current without preheating the test sample by pulsing the output current at high currents.

The SPI system also has the unique ability to turn on at the current zero crossing every time for any load by automatically adjusting the output firing angle. This eliminates DC offset for every circuit breaker type and the need for the user to determine and adjust the firing angle for different loads and circuit breakers.

The Megger SPI225 is a reliable secondary injection tester used for testing protective relays and circuit breakers. It offers accurate simulations and is great value for money. SPI225 N1A is the advanced model of SPI225 series. The primary injection test simulates a high current, while the secondary injection test uses a low-level signal.
