Details

The MT577 10kV Diagnostic Insulation Tester with increments of 50V on each range will automatically discharge the circuit after the test has been completed. Using the range button switches, 6 preset ranges of 250V, 500V, 1000V, 2500V, 5kV and 10kV can be selected, with an insulation resistance up to 35TΩ. The microprocessor controlled MT577 has the capability of being a diagnostic tool and is intended for testing insulation on Rotating Machines, Transformers, Cables, High Voltage Generators, Electric Circuits and Surge Arresters. The short circuit current output is up to 6mA. It has the function of measuring Absorption Ratio and Polarization Index of AC voltage and DC voltage and 500 test measurement results can be saved in the memory of the meter and recalled onto the LCD display. The large backlit LCD display indicates the readings of insulation, measuring time, output voltage and output current. The MT577 can measure up to 750V AC and up to 1000V DC and Capacitance up to 50μF, and is housed in a robust case ideal for extended field use, powered by 12.6V Lithium batteries. Stored data
can be transferred to a PC using an optical USB and software supplied.
