Product introduction:
The six-phase relay protection calibrator is a high-intelligence, multi-function relay protection calibration instrument developed by our company on the original basis. The instrument adopts microcomputer technology and is composed of a single-chip microcomputer, a logic control unit, an AC-DC current and voltage output unit, a high-precision data acquisition unit, an LCD liquid crystal display, a real-time clock, a printer, etc. The measurement accuracy is high and the repeatability is good. The instrument also has the advantages of beautiful appearance, reliable performance, simple operation, complete functions, etc. It is an ideal testing instrument for verifying relay protection devices.
Six-phase relay protection calibrator can test a variety of AC and DC current, electricity, room, signal, reclosing, differential and other single relay and the entire group of relay protection screen, can test the various relays pull-in voltage (current Values, release voltage (current) value, pull-in time and disconnection time of various contacts (normally open, normally closed, changeover, delay) are automatically tested three times, the mean is calculated three times automatically, and test results can be printed .
