Technical Features

Test Voltage

0 - 12 kV

Rated Current


Automatic Balancing through windows based software

Automatic & software controlled voltage setting to avoid abrupt voltage rise.

Automatic selection of seven different modes of operation for measurement of 3 terminal object from windows based software.

1) UST-Ungrounded Specimen Test - 3 Combinations

This mode is used when the object under test is not grounded

This test provides most accurate results

1) GST-Grounded Specimen Test

This mode is used when the object under test is permanently grounded

This test is used more often in outdoor installations, power systems etc.

1) GST-Grounded Specimen Test with guard. 3 Combinations

This mode is used for measuring them stray capacitances and separating them from basic measurement in GST mode.
