Insulation resistance measurement between VSD and SUT

Post by Arkad »

Good day - question. The VSD measures insulation resistance (with or without a downhole monitoring system (TMS)) between the VSD and the SUT (basically the jumper). Some people say R is only measured after the SUT. Which is it?

День добрый, возник вопрос. СУ производит замер сопротивлений изоляции (с тмс либо без него) между СУ и ТМПН (по простому перемычка). Кто то говорит что R измеряется тока после тмпн.

Insulation resistance is measured only after the SUT.

Сопротивление изоляции измеряется только после ТМПН.
