Product DescriptionTest Function
Manual Test:The manual test can output three AC voltages and three AC currents, and the amplitude, phase, frequency and sequence component of the AC quantity can be controlled manually by step size.
State Sequence Test:Status can be carried out action time test, multi-state simulation of failure, up to 5 states can be set, can be simulated after re-closing acceleration, can also be combined with the company's wechat analog circuit breaker for backup self-firing test.
Low Cycle Load Shedding Test: The unit can perform fixed point test for low cycle load shedding action value, action time, slip lock value, voltage lock value, current lock value.
Concurrent Test: The unit can test the relevant indicators of the test concurrent device
Harmonic Unit: The unit can be used for the second harmonic inrush current blocking test of transformer differential protection.
Cross Sampling Test: This unit is mainly used to measure the sampling accuracy of the AC sampling device.
Remote Test: The unit can quickly open two pairs of nodes, the intermediate interval time can be freely set, the minimum resolution of 1ms.
Millisecond Meter: The unit can cooperate with the scene to do some open quantity, flip timing.
The specific functions are described as follows:
Manual test functions | Can arbitrarily set the AC amount of various voltages, current amplitude, phase, and set various fault types of parameters |
