UIV-M-(15, 50, 100, 150) kV Mobile Test Sets
UIV-M sets are designed for use as part of mobile test laboratories.
As distinct from portable UIV sets, all h.v. elements of UIV-M sets are mounted on common frame in form of one whole high voltage block and connected with corona-free bus; these sets have grounded control panel in form of standard 19-inch metal case-crate.

IPG-100 insulator
IPG-100 removable wall entrance, SF6–filled insulator is designed for output of test voltages, generated by UIV-M sets, from mobile laboratory to test objects.
In “test position” the insulator is installed in hole in the high voltage section wall jf mobile laboratory by means of special sealed flange:
In transport position the insulator should be latched inside the section by means of special holder, and hole in the section wall should be closed by sealed cover:
USZ-100 automatic grounding device
Automatic grounding device type USZ-100 is designed for mobile test laboratories on the basis of two damping resistor type RD 100/15.
Two RD 100/15 resistors can be discharge energy of 18000 Joule
Device electromechanical drive is controlled by set control panel:
- USZ-100 switching-off – at set main contactor switching on;
- USZ-100 switching on – at operating contactor switching off: manually or automatically – at test insulation breakdown or flashover

After USZ-100 actuation (switch-on) with 0.1 second delay, set control panel provides actuation of mobile laboratory main ("dumb") earthing device.
