It is planned to install the SSM Mini 4-Channel, On-line Partial Discharge (PD) Portable Monitors onto ten 11kV feeders from both the North and Southern networks. The SSM Mini Monitor is designed to detect the PD in MV switchgear and the associated 11kV cables. Therefore it will be used as a monitoring device which will record the PD level in its memory storage for viewing purposes where results can be monitored both remotely and locally.
The project has the following objectives:

  • By deploying ten of the SSM Mini Monitors on 11kV feeders, PD trend analysis will be possible as results are stored both locally and remotely

  • To prove that the SSM Mini Monitors are able to monitor for PD activity in primary substations on both MV switchgear and 11kV cables

  • Understand the analysis obtained from the SSM units and distinguish between low levels of PD activity that would require regular monitoring and severe levels that will warrant replacement for the switchgear / cable

  • By integrating the PD test and monitoring technology within a condition-based asset management approach, electricity.
