SXZB Relay Protection Tester
The SXZB Series Relay Protection Tester is a compact microcomputer-based test system designed for testing and commissioning protective relays and relay protection devices. It is suitable for electrical power systems, substations, power generation facilities and relay testing laboratories where reliable current and voltage signal outputs are required.
The tester integrates a high-speed digital signal processor, true 16-bit DAC module and high-fidelity high-power amplifier. It can operate independently or be connected to a laptop computer, while the built-in industrial computer display and rotary mouse controller provide convenient operation for relay protection testing, signal output and test data management.
