Portable partial discharge analyser targets faster high-voltage diagnostics

Megger has introduced the ICMneo, a new portable partial discharge (PD) measurement system designed to simplify the testing and condition assessment of medium- and high-voltage electrical assets.

Developed for use in both factory and field environments, the battery-powered instrument provides up to five hours of operation and incorporates four simultaneous measurement channels, allowing engineers to monitor multiple assets during a single test. Advanced noise-gating technology is designed to minimise electrical interference, helping to improve the accuracy of measurements in challenging industrial environments.

The ICMneo complies with IEC 60270, the international standard for partial discharge measurement, making it suitable for applications including factory acceptance testing, post-repair verification and in-service condition monitoring.

A seven-inch touchscreen provides access to measurement and analysis functions, while the compact, rugged design is intended to withstand demanding site conditions. The instrument can be used to assess a wide range of medium- and high-voltage equipment, including transformers, insulators and rotating machines.

By combining portability with multi-channel measurement capability, the ICMneo aims to provide maintenance engineers and test specialists with a practical tool for identifying insulation defects and supporting informed maintenance decisions across critical electrical infrastructure.
