Newly available from Megger , the MTO210 transformer ohmmeter makes measuring the DC resistance of all types of magnetic windings quick, safe and accurate.
Also ideal for checking the operation of on-load tap changers, the MT0210 transformer ohmmeter offers users reduced test times, fast discharge times, and built-in demagnetisation circuitry.
The MT0210 has an abundance of timesaving features, including:
- dual channel operation - allows the resistances of transformer primary and secondary windings to be measured simultaneously
- bi-directional current output capabilities - allow users to take advantage of any existing magnetization in the winding core to help with rapid current stabilisation.
For additional safety, the MT0210 transformer ohmmeter includes circuitry that automatically discharges the winding or windings when either the test is completed, a lead is accidentally disconnected, or there is a power failure.
These transformer ohmmeters also offer facilities for demagnetising winding cores before or after resistance testing is carried out. They can also be used as a standalone core demagnetizer.
Used most effectively in the upkeep of winding resistance measurements, the MTO210 transformer ohmmeter allows subsequent test results to be compared to established benchmarke results to determine if changes are occurring in the transformers and associated voltage regulators, control wiring etc.
