ORPD-H4D Partial Discharge Detector
I.Product introduction
ORPD-H4D partial discharge detector is a multi-functional handheld instrument, which adopts the current popular Android system. Based on ultrasonic and high-frequency current detection methods, it can observe the measurement signal in multiple cycles, identify the frequency of discharge, and analyze it through multiple modes. It can clearly judge the fault and is suitable for partial discharge detection of electrical equipment such as GIS, switch cabinets, transformers and power cables.
