Worldwide Launch of MTO250 - 50 A Winding Resistance Test Set

We are pleased to announce the addition of the MTO250 to the Megger winding resistance family.

This new unit is able to output up to 50 A of test current with 50 V compliance voltage while maintaining the same size and weight as previous models. It can also test large transformers up to 10 times faster than traditional 10 A models.

Other notable features include:

• Remote computer control
• Advanced demagnetization capability
• Simplified interface for On Load Tap Changer (OLTC) testing
• 30, 60 and 100 ft lead sets available
• Universal Kelvin lead sets available

Unlock the Power of the MTO250
Sign up for our webinar Improvements in Transformer Winding Resistance Testing on Friday, Oct 16, 2015 at 10AM Central Time to learn more about applications of the new MTO250.

MTO250 Worldwide Launch
With the new MTO250, we now have the beneficial capability of testing large transformers up to 10 times faster than a traditional 10 amp model. We have increased our current output by a factor of five, while maintaining the same weight as most 10 amp models.

In response to market needs, we have added a requested feature – Remote Computer Control. This gives customers improved efficiency in testing as well as an easy to use method for producing test reports. While adding this feature, we have also added the ability to automate “Heat Run” testing via software. This is a benefit which decreases the critical test time needed to perform this test.

The demagnetization capability of the MTO250 has been enhanced and we are now able to get transformers to a closer state of balance than our previous models. While improving our capability, we have reduced our demagnetization time. This will give customers more confidence in placing their transformers back into service without false trips due to magnetized transformer cores.

Customers have been asking for higher test current in winding resistance testing, so as to improve productivity (faster testing) in the field and in the shop. Most competitors have offered the higher current, but at a higher cost and at a heavier weight. With most competitors, this has reduced portability and brought weight close to allowable safety limits within standards.

While testing is similar to our traditional models, we have SIMPLIFIED the interface to better guide users through the long Load Tap Changer (OLTC) test process. This is done through improvements in the front panel where stored results are now displayed so operators can view progress when testing multiple results.

The new MTO250 has various lead sets available able to test transformers up to 765 kV. Customers have the flexibility to order complete lead sets, available in 30 ft (9m), 60 ft (18m) and 100 ft (30m) lengths, or can purchase our newly designed individual universal Kelvin lead sets.
