Megger PD Scan – Online Partial Discharge Handheld Scanner
- Perfect for detecting partial discharge early which ultimately will protect your assets
Electrical insulation failure is one of the leading causes of costly equipment breakdowns in substations. Partial discharge (PD) is often the first sign that insulation is deteriorating. If left undetected, it can develop into major faults, endanger staff, and even cause widespread outages across entire networks.
The Megger PD Scan is a portable, easy-to-use megger pd scanner designed to detect partial discharge activity quickly and reliably. With its advanced sensor technology and smart features, it helps operators identify potential issues before they escalate into serious failures.

Why Choose the Megger PD Scan?
The megger pd scan provides a safe, cost-effective way to survey equipment for PD activity without the need for shutdowns. Unlike traditional offline testing, which requires a complete system outage, this handheld scanner allows you to work under normal operating conditions. This means you can protect your network and keep operations running smoothly while gathering essential data.
Key benefits include:
- Early fault detection – spot PD activity before it leads to breakdown.
- No shutdown required – test switchgear and cables live.
- Safer working environment – identify risks before maintenance begins.
- Universal application – suitable for MV and HV substations, switchgear, and cables.
- Time and cost savings – allocate maintenance resources precisely where needed.
Wide Range of Applications
Thanks to its variety of sensors, the megger pd scanner can be used in multiple environments:
- Medium Voltage Switchgear – Internal and external sensors measure PD activity inside encapsulated and air-insulated switchgear.
- Cables – The detachable HFCT sensor attaches around the earth screen, giving a quick overview of cable condition.
- Outdoor Equipment – With the parabolic acoustic receiver and laser pointer, you can pinpoint surface discharges and corona on HV components with high accuracy.
Smart Features for Simple Operation
The megger pd scan has been designed with user convenience in mind.
- Plug & Play Sensors – Auto-recognition prevents connection errors.
- Touchscreen & Soft Keys – Operated like a smartphone, quick shortcuts simplify navigation.
- Visual Feedback – Measurement data is automatically analysed and displayed using clear symbols such as smiley faces, so results are easy to understand.
- Integrated Camera & QR Scanner – Capture images of defects and scan asset codes directly into your test report.
- Environmental Monitoring – Built-in temperature and humidity sensor ensures results are accurate and conditions are documented.
- Wireless Headphones – Optional Bluetooth® headset for comfort and safety in the field.
Reporting Made Easy
Creating professional reports is straightforward with the included MeggerBook RE software. All data, photos, and QR code references are automatically saved and can be compiled into clear, detailed documents in just a few clicks. This makes reporting faster, reduces admin errors, and provides evidence for regulatory compliance.

❓ Frequently Asked Questions (FAQ)
Q1: What is partial discharge (PD)?
A. Partial discharge is a small electrical spark inside insulation. Over time, repeated PD activity damages insulation, eventually causing equipment failure.
Q2: Can the Megger PD Scan be used while equipment is live?
A. Yes. The scanner is designed for use under normal operating conditions, so you don’t need to shut down your system.
Q3: How does the device present results?
A. Results are analysed automatically and displayed in an easy-to-understand format, including graphical symbols such as smiley faces to indicate condition.
Q4: Is the Megger PD Scan suitable for outdoor use?
A. Yes. With the parabolic acoustic sensor, it can accurately detect corona and surface discharges on outdoor HV equipment.
Q5: How long does the battery last?
A. The rechargeable Li-ion battery provides more than eight hours of continuous use.
