Photo of the constant current test set UIVPT-200

This special device is intended for testing insulators following requirements IEC 61325 (1995) with standart (GOST 1516.2) normative constant voltages up to 200 kV. Device provides measurement of values of test voltage in processe of the tests according to requirements of measurement systems for high voltages GOST 17512 (IEC 60060-2).
IEC 61325(1995) Insulators for overhead lines with a nominal voltage above 1000 V - Ceramic or glass insulator units for d.c. systems - Definitons, test methods and acceptance criteria.

This device represents placed on a non-standard frame: transformer IOG-100/7,5 , rectifier and voltage divider DN-200EO. For convenience of movement the frame is equipped with wheels. Couple of rotary wheels are supplied with a stopper. Device controlled by standard PU 220-11/4,4 (T) or PU 220-21/4,4 .
