The OMS 605 is a portable partial discharge (PD) monitoring system designed for inspections of high-voltage assets under load. It can be employed for temporary and periodic, condition-based monitoring. Measurements are performed at the assets one after the other. The OMS 605 can be easily connected to existing sensors installed at the asset, e.g. coupling capacitors or high frequency current transformers.
The portable system has three channels in order to capture partial discharge activities at all three phases. The PD acquisition is performed synchronously, which simplifies the suppression of noise signals and the individual evaluation of particular PD sources.
