Megger MTO210 Transformer Ohmmeter

The Megger MTO210 Transformer Ohmmeter is a specialized instrument designed to accurately measure the winding resistance of transformers, a critical aspect of transformer maintenance and diagnostics. This device is particularly valuable for identifying potential issues in transformer coils, such as shorts, poor connections, and winding damage.

The MTO210 is highly effective for assessing the windings and contact resistance of tap changers with ‘make-before-break’ contacts and voltage regulators. It is particularly valuable for detecting pitted or misaligned contacts, as the device will alert the user if these issues are present. Additionally, it includes an auto-shutdown feature for enhanced safety. Should there be any accidental disconnection of a test lead or a power loss to the instrument, it will automatically discharge any stored energy in the unit under test (UUT) to ensure safety.
