Protective 6 Phase Relay Testing Equipment for AC DC Signal Injection and Relay Response Time Measurement
Product Description
SXZB 6 Phase Relay Protection Tester
The SXZB Series Portable Protective Relay Test Set is a compact testing platform developed for engineers working with relay protection systems. It provides current and voltage signal outputs together with switching and timing interfaces for testing protective relays used in power utilities, substations and electrical facilities.
The equipment integrates a high-speed DSP, true 16-bit DAC, high-fidelity power amplifier, industrial computer display and rotary mouse controller. Its standalone operating mode provides convenient field use, while laptop connectivity allows computer-assisted testing when required. The system can therefore be used for relay commissioning, maintenance and laboratory testing.
