Description
The Megger SPI4000 supplies regulated high AC current for primary injection testing of large circuit breakers and protection systems.
Automated current control and digital timing support pickup and time-current testing without continuous manual adjustment. Output arrangements accommodate different test impedances, while stored test information supports reporting. The maximum 40 kA output is a short-duration rating; input supply, connections and cooling intervals determine the usable test sequence.
