Overview The intelligent relay protection tester 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.
Intelligent relay protection tester This instrument can test a variety of AC and DC current, voltage, signal, reclosing, differential and other single relays and the entire set of relay protection screen, can test the various relays pull-in voltage (current) Values, release voltage (current) values, pull-in and break-off times for various contacts (normally open, normally closed, changeover, delay) are automatically tested three times, the mean is calculated three times automatically, and the test results can be printed.
