Real-Time Cable PD Monitoring System with APM, RM EYE

Overview

A prominent industrial customer in the Asia-Pacific region has made a strategic decision to implement RM EYE, our advanced APM system designed for managing electrical infrastructure. This initiative includes conducting online partial discharge measurements on a 220kV cable circuit. The project utilizes high-frequency current transformer sensors, which are specifically chosen for their precision and reliability in detecting potential insulation failures. By adopting this cutting-edge technology, the customer aims to enhance the safety, efficiency, and longevity of their power distribution network, while proactively mitigating the risks associated with partial discharge events.

The Challenge

Localized discharges resulted in dielectric losses, chemical reactions, and noise, all of which contributed to the degradation of the insulation over time and ultimately compromised the cables’ overall integrity:

Thermal stress

Partial discharges produced heat, leading to localized thermal stress points along the cable's length.
Equipment damage

Some might result in arcing and flashovers, causing fires, explosions, and ultimately asset damage.
Reduced grid efficiency

Reactive strategy to identify and monitor PD activity maximized downtime and reduced the overall grid efficiency.

The Rugged Monitoring Solution

Rugged Monitoring’s partial discharge monitoring for power cables assessed the insulation condition at critical locations and provided advanced analysis using RM EYE:

HFCT PD Sensor

Durable split-core HFCT sensor for detecting and analyzing PD signals.
UHF PD Edge Device
