Smart primary injection test system

Enabling accurate and repetitive tests of high-current breaking devices through adaptive current injection

The SPI500 is a powerful and versatile testing system designed to meet the demanding needs of substation testing. It can handle a wide range of high-current tests, including those for electronic reclosers, circuit breakers, high-speed fuses, and ground fault relays. 

With the ability to control up to two SPI500B boosters, the SPI500 can increase its testing capacity by up to three times. Its unique control system ensures accurate and reliable testing, even under changing load conditions. 

The SPI500 offers both manual and automatic control options, with the Smart Touch View Interface (STVI) providing easy-to-use manual control and the PC-based control system enabling fully automated testing and report generation.

The SPI500 can test self-powered reclosers like the S&C Tripsaver with the push of one button. Also, the most portable test set for testing breakers under 600 A or for testing Modified Differential Ground Fault schemes (MDGF).
