IS-PDS-MH165
In oil-immersed transformers that use insulating materials such as insulating oil, insulating paper, and pressboard, insulation breakdown caused by manufacturing defects or aging degradation can lead to initial partial discharge, which, over time, weakens the insulation strength further and may result in unforeseen major accidents. IS-PDS-MH165 is a manhole-mounted sensor that connects to a system for early detection of transformer insulation degradation and measures partial discharge (PD) inside the transformer. It has enhanced sensitivity to accurately detect partial discharge signals in the UHF band and demonstrates excellent performance in reducing external noise.
