⚡ For commissioning engineers, no two days on site are ever quite the same — and test equipment needs to keep up.

That’s where the 200ADM-P Mk2 proves its value.

Built to handle everything from low-current injection to high-current testing, relay timing, waveform capture, AC/DC measurement and more, it gives engineers the flexibility to perform multiple tests with one reliable instrument.

In real-world commissioning work, that means less switching between equipment, faster testing, and greater confidence in the results. ✅

The 200ADM-P Mk2 continues to support engineers across a wide range of power system applications, helping make complex testing simpler and more efficient.

We are also looking forward to featuring the 200ADM-P Mk2 in the remaining workshops this year with PASS Ltd, where attendees will be able to see it in action. 👏

⚡ Bigger is not always better — especially when you have to carry it around site all day.

For many relay testing applications, engineers simply do not need a large, heavy 100A test set. But traditionally, that has often been the only option available.

The 50ADM-P changes that.

Designed for portability without compromising capability, the 50ADM-P delivers:

✔ Up to 50A output current
✔ Precise relay and breaker testing
✔ Advanced timing functions
✔ USB data storage
✔ True RMS metering with waveform capture
✔ Compact, easy-to-carry design

Perfect for commissioning, maintenance, and protection testing, it gives engineers the functionality they need — without the unnecessary weight.

Less bulk. Less strain. More efficient testing.

High-voltage testing & commissioning at our hands-on workshop!

⚡ What happens if insulation fails under voltage?

In high voltage systems, insulation breakdown can lead to equipment damage, outages, and safety risks.

That is why testing is essential before anything is energised.

The KV30-40D MK4 High Voltage Test Set allows engineers to safely and accurately test insulation strength:

✔ Variable output up to 30kV
✔ True RMS voltage and current measurement
✔ Adjustable trip protection to prevent damage
✔ Timed test sequences for consistent results
✔ Safety interlocks for secure operation

By simulating real electrical stress, weak insulation can be identified early — before it leads to failure in service.

This is exactly why such equipment has been trusted and proven in the field worldwide for decades.

⚡ Behind every successful HV shutdown is thorough, methodical testing.

Great to see Jaguar Building Services Ltd. delivering comprehensive maintenance across HV switchgear, including:

✔ Full relay testing (Schneider Sepam S80 & T20)
✔ Verification of external trip circuits (REF, EPO, intertrips)
✔ Confirmation of VCB trip and latch operation
✔ Accurate labelling aligned with protection functionality

Our 100ADM Pelicase Secondary Injection Test Set was used as part of this process — helping engineers validate protection performance with confidence.

In environments like this, there is no margin for error. Proper testing ensures systems respond correctly under fault conditions, preventing damage and ensuring safety.

👏 Well done to everyone involved.

⚡ What happens if a protection system doesn’t trip when it should? ⚡

In high voltage environments, that risk is not acceptable.

Primary current injection testing ensures that everything works together — CTs, relays, and breakers — before a system is energised.

The CU-Ps Mk2 Primary Current Injection Test System is designed for exactly this purpose:

✔ High current output up to 6000A
✔ Accurate timing measurements down to 1ms
✔ True RMS metering for reliable readings
✔ Data capture for reporting and analysis

By identifying issues early, engineers can avoid faults, prevent damage, and ensure safe operation from day one.

That is why equipment like this is essential in commissioning and maintenance work.

⚡ Safety starts before the system is energised ⚡

When working on overhead lines, engineers must be certain that cross arms and insulators are safe. There is no room for guesswork.

The MCAT+ Micro Cross Arm Tester is designed to do exactly that — helping identify insulation faults and assess safety before work begins.

✔ Detects faulty insulators
✔ Measures short circuit current (ISC)
✔ Provides clear pass / caution / fail indications
✔ Built-in safety features to protect users

Compact, portable, and built for real-world conditions, it is a trusted tool for field engineers working in demanding environments.

At T&R Test Equipment Ltd., helping engineers stay safe is always the priority.
