ZXJB Single Phase Relay Protection Tester
ZXJB single-phase relay protection integrated tester adopts new power supply technology for AC and DC voltage and current sources, which provides convenience for field personnel to use power supply instrument technology for other experiments. The function can perform various checks on various common relays, and the panel layout is exquisite, allowing the operator to operate easily and at a glance, thus winning the unanimous praise of the majority of users.
Manual
Video1. Measuring relay: measure start value, return value, and their factors of current, voltage type relay.
2. Time relay: Measure start value, return value and action time, error less than 0.2ms
3. Intermediate relay: Measure start value, return value, holding value and operation time of coil intermediate relay.
4. Reclosing relay: Charge test of capacitance, charge time, reclosing time and intermediate member test.
5. Differential relay: DC Excitation test, Braking test, Volt-ampere characteristic test.
