Product Description
6 Phase Relay Protection Tester
Designed for modern relay protection testing, the SXZB Series Digital Relay Protection Test System provides AC and DC current and voltage outputs for evaluating protective relay operation. It is intended for electrical power system testing, relay commissioning and maintenance where flexible test signal generation is required.
The system adopts a high-speed DSP processor, true 16-bit DAC and high-power high-fidelity amplifier, together with an industrial computer display and rotary control device. Engineers can perform signal injection and switching-related tests while using the integrated timing measurement function to evaluate relay response during commissioning and maintenance work.
