⚡ Small package. Serious testing power!

Meet the DMO200 Digital Micro-Ohmmeter.

Weighing just 6.9 kg, this compact instrument delivers up to 200 A DC for low-resistance measurements across a wide range of applications.

🔧 Testing busbar joints?
🔩 Checking welds and bonding connections?
⚡ Measuring circuit breaker contact resistance?

The DMO200 is built to handle these jobs and more.

A few reasons to like it:

✅ Up to 200 A DC output
✅ 0.1 μΩ resolution
✅ 100 A continuous output
✅ Three programmable test currents
✅ USB result storage and CSV export
✅ Colour display for current, voltage and resistance

Now, our Sales & Marketing team occasionally gets curious. So, we connected several smaller test leads to create a combined length of 45 metres.

The cables put up resistance. The DMO200 wasn't having any of it! 😅 It completed the full test sequence, delivered the expected results and even correctly flagged errors when we deliberately introduced incorrect connections.

We might leave the next experiment to the engineers!

🔌 Why would you need a TPT9000?

Because checking transformer polarity before commissioning matters!

The TPT9000 Transformer Polarity Tester helps identify incorrect current and voltage transformer connections quickly and easily.

✔️ Simple plug-and-play operation
✔️ Automatic detection
✔️ Built-in proving unit
✔️ Lightweight design with a magnetic back

💪 And it's tougher than you might think! Our marketing team dropped one from the roof, and it still worked. We don't recommend trying that at home, though! 😅

⚠️ Important: The TPT9000 is designed for dead systems only. Always ensure the equipment under test is powered off before connecting.

⚡ A protective relay might spend years doing almost nothing. Then, in a fraction of a second, it may become one of the most important devices in an electrical system.

Protective relays are designed to detect abnormal electrical conditions and initiate the appropriate response.

But what happens if the relay has not been tested properly?

A fault occurs, but the relay does not respond at the expected current.

Or it responds too slowly.

Or the protection operates when it should not.

The consequences can be much bigger than a failed test result.

🏭 In industry, an electrical fault could bring an entire production line to a standstill.

🚆 In transport infrastructure, a protection problem could contribute to disruption of critical services.

⚡ In power networks, equipment may be exposed to fault conditions for longer than intended.

💡 And ultimately, failures within electrical infrastructure can affect the electricity supply relied upon by homes, businesses and essential services every day.

This is why relay testing is not simply a box-ticking exercise.

Engineers need to verify that protection systems respond as designed, with the correct electrical conditions and within the required time.

The 50ADM-P Secondary Current Injection Test Set provides a controlled way to test protective relays and associated equipment, with current outputs up to 50 A, voltage outputs up to 18 V, accurate true RMS metering and timing resolution down to 1 ms.

It can be used across a wide range of protection applications, including overcurrent, ground fault, under/over voltage, negative sequence, directional power and IDMT overcurrent relays.

It also allows test results to be stored and exported for further analysis and reporting.

Because when a protection system is needed, there is no opportunity to test it for the first time.

Test it properly before the fault happens. ⚡
