Portable partial discharge monitor ICMneo

Overview
Compact multi-channel digital partial discharge (PD) measurement instrument for medium-voltage (MV) and high-voltage (HV) insulation assessment. Stand-alone, battery-operated unit with an integrated 7" touchscreen and a modular design compatible with Megger PD accessories. Suitable for factory acceptance testing, post-repair evaluations, end-of-line quality assurance and on-site spot or continuous testing. Complies with IEC 60270.

Key capabilities

• Up to four real-time parallel measurement channels for simultaneous diagnostics.
• Integrated 7" touchscreen for intuitive operation.
• Battery-operated portability with up to 5 hours runtime; mains-operable as alternative.
• Advanced PD analysis including spectrum analysis, UHF measurement modes and PRPD display.
• Noise gating and signal processing to minimise external interference and distinguish PD signals from noise.
• Real-time data capture and continuous monitoring for immediate interpretation.

Applications

• Testing of MV/HV assets: bushings, spacers, cable accessories, instrument transformers, distribution transformers, rotating machines and MV/HV cables.
• Factory acceptance testing (FAT), post-repair checks, end-of-line quality control and field spot testing (online/offline).

Accessories and modularity
Compatible with Megger PD accessories including pre-amplifiers, coupling capacitors, quadrupoles, disturbance antennas and HFCTs. Common accessories are available separately to configure tests for specific asset types.

Additional functional notes

• Phase-resolved PD patterns (PRPD) and PD magnitude indicators to assist defect type and severity assessment.
• Spectrum analysis highlights frequency ranges of PD activity for in-depth diagnostics.
• Optional DAkkS-calibrated voltage measurement for enhanced accuracy.
• Troubleshooting and maintenance features such as adaptive calibration routines and advanced noise handling.
