Megger ICMneo
Digital Partial Discharge test and measurement device
Compact multi-channel digital PD measuring device for medium voltage and high voltage insulation assessment, offering reliability, precision, and flexibility. Flexibility combines with all PD accessories from Megger. Easy to operate, stand-alone, with high modularity.
The ICMneo is a state-of-the-art, stand-alone digital partial discharge (PD) measurement device designed to evaluate the condition of medium and high voltage insulation. Engineered for reliability and precision, it’s suitable for factory acceptance testing, post-repair assessments, and end-of-line quality assurance, as well as online and offline spot testing on site. This battery-operated device features a 7” touchscreen for intuitive operation and supports up to four parallel measurement channels. Its modular design and advanced capabilities make it a versatile solution for measuring any MV/HV asset including bushings, spacers, cable accessories, instrument transformers, distribution transformers, rotating machines, electronic components e.g. IGBTs. By identifying insulation defects at an early stage, the ICMneo helps prevent costly breakdowns, ensures system efficiency, and supports compliance with the latest IEC 60270 standard.
Megger MPAC208
Professional Acoustic Imaging Camera
About the product
The MPAC208 is a professional-grade acoustic imaging camera designed for fast, accurate detection of ultrasonic sound sources across industrial environments. It helps maintenance teams identify gas leaks, mechanical deterioration, and partial discharge (PD) in high-voltage electrical systems, without needing to interrupt operations.
At its core is a 208 channel MEMS (micro-electromechanical system) microphone array offering sensitivity across 2 kHz to 100 kHz, enabling the MPAC208 to detect even very small leaks and subtle ultrasonic patterns.
The acoustic data is fused with a 13 MP optical camera and displayed on an 8-inch capacitive touchscreen, presenting clear, real-time visual overlays that make sound sources immediately visible.
The MPAC208-IECEx camera provides all the features seen in the standard MPAC208 but is certified for use in Class 2 explosive atmospheres.
Designed for real industrial environments
With a detection range up to 200 m, the MPAC208 is suitable for both close-proximity inspection and stand-off safety at substations, switchgear, or during overhead line work.
The Focus function suppresses background noise, allowing operators to isolate target sound sources even in loud plants or workshops. SoundScan™ directional guidance assists in locating leaks that are outside the visible frame, helping technicians trace issues quickly
Three core operating modes
- Gas Leak Mode: Automatically estimates leak rate, cost impact, and distance to the source, helping prioritise repairs and quantify energy loss.
- Partial Discharge Mode: Captures PD activity and provides PRPD (Phase Resolved Partial Discharge) analysis, supporting early detection and classification of discharge types.
- Mechanical Mode: Identifies bearing wear, valve leakage, cavitation, and vibration-related wear patterns through ultrasonic signatures.
Megger ICMObserver
Partial Discharge Monitoring System
The ICMobserver combines the unmatched quality of the analogue front end of our current PD detectors with the additional features and benefits of the developments in digital signal processing during the last 20 years.
The ICMobserver is a versatile state-of-the-art monitoring system, which combines four devices in one solution: A spectrum analyser, a time domain oscilloscope, voltage measurement, and a PD monitor.
With the digital signal processing, the spectrum analyser offers a vast range of possible bandwidths. This greatly improves capabilities to deal with an elevated noise-floor that is inevitable in on-site monitoring conditions.
The built-in time domain oscilloscope together with fully parallel phase-resolved partial discharge patterns (PRPD) on all channels significantly expands the analysis options, so that you will be able to give an in-depth analysis of the condition of the monitored asset.
The modular concept of the hardware and software ensures expandability of the system for future applications, e.g., dissolved gas analysis (DGA) monitoring and temperature and load surveillance providing one data aggregation point.
- Versatile partial discharge (PD) monitoring system for medium and high voltage assets
- Fully parallel voltage and PD measurement on all channels
- Remote access and analysis options
- State-of-the-art digital signal processing for an immediate data display and in-depth analysis without the need for further equipment
- Partial discharge measurements according to IEC 60270
