Need a clearer picture of what’s happening with your power?

The Acksen Electrocorder EC-7VAR-RS logs three-phase voltage, current, power factor and energy usage, giving you the data you need to identify issues, understand consumption and make better-informed decisions.

Ideal for electrical contractors, facilities teams, utilities and maintenance engineers, it can help with:

• Energy usage monitoring
• Voltage and current investigations
• Solar PV and UPS sizing
• Standby generator sizing
• Identifying whether low voltage is linked to high site demand

With flexible Rogowski coils and simple software that turns recorded data into easy-to-read graphs, the EC-7VAR-RS makes detailed power monitoring straightforward.

Cable testing in the middle of a busy city needs to be efficient, mobile and easy to manage.

Megger’s Centrix City and Centrix City Compact vans bring cable testing, diagnostics and fault location together in purpose-built mobile systems for low and medium voltage networks.

Built around the SPG 40 test set, they support everything from testing and fault prelocation through to pinpointing and fault burning, with Megger’s easyGO operating philosophy helping simplify operation.

Seven cable fault location technologies. One centrally controlled system.

The Megger PRIMEON brings fault location, testing and optional diagnostics together in a highly configurable cable test van system.

From insulation resistance testing and TDR through to HV prelocation, fault conversion, thumping and sheath fault pinpointing, PRIMEON gives operators access to seven individual technologies through one intuitive central interface.

With automated motorised HV switching, remote access and integrated MeggerBook V2 software, it’s designed to make complex cable fault location more streamlined and efficient.

Whether your focus is fault location, testing, diagnostics or a combination of all three, PRIMEON can be configured around your requirements.

Choosing a partial discharge monitoring system isn’t simply about picking the most advanced technology - it’s about choosing the right approach for the asset and the application.

Permanent online monitoring, portable systems and laboratory testing equipment each have their place, depending on asset criticality, required sensitivity and your wider maintenance strategy.

Megger’s latest article looks at the key factors to consider when selecting a PD monitoring solution, including different asset types, signal-to-noise performance, integration requirements and ongoing technical support.

Are you greasing your bearings because they need it - or because the schedule says it’s time?

The Adash A4910 Lubri helps take the guesswork out of lubrication by monitoring bearing vibration while grease is being applied.

Simply mount the sensor, start greasing and watch the vibration level change. Once the value stops decreasing, you know when to stop.

That means less risk of over-greasing, less wasted grease and a more condition-based approach to bearing maintenance.

Smarter lubrication. Better control. Longer bearing life.

Choosing the right MV cable test method matters - because not every excitation voltage is suited to every application.

In this article, Megger compares four essential methods used in cable testing and diagnostics:

DC voltage
0.1 Hz VLF Sine
VLF cosine-rectangular / 50 Hz Slope
Damped AC (DAC)

Each offers different advantages depending on whether you’re carrying out sheath testing, withstand testing, tan delta measurements or partial discharge diagnostics.

Understanding where each method performs best can help improve test accuracy, reduce unnecessary cable stress and support more informed maintenance decisions.

Powerful MV cable testing and diagnostics - without the need for a bulky setup.

The Megger VLF Sine Wave 62 kV is a compact, portable system designed for testing and condition assessment of medium-voltage cables.

It combines multiple capabilities in one field-ready unit, including:

VLF and DC withstand testing
Sheath testing and sheath fault pinpointing
Optional integrated Tan Delta diagnostics
Automatic test frequency adjustment based on cable length
Testing of 35 kV rated cables up to 25 km
Automatic result interpretation to IEEE 400.2

With a large colour touchscreen, onboard data storage and no external computer required in the field, the VLF Sine Wave 62 kV makes testing, evaluating and recording results straightforward.

A 1.5 km railway signalling cable. A hidden fault. And the challenge of finding exactly where the problem was.

In this Megger application note, see how the STX40 was used to test, prelocate and pinpoint a fault in a multi-core signalling cable — ultimately identifying a defective joint at approximately 1,079 metres.

The case demonstrates how multiple fault location methods can work together to deliver accurate results, even on smaller cross-section, lower-voltage cables used in railway applications.
