Transformer Resistance Testing
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the Megger Transformer Ohmmeter (MTO) series of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

Earthing Resistance Tester
JYD-10A
transformer neutral grounding resistor is the vital need in medium voltage AC distribution network that are also called by different names like Neutral Earthling Resistors. They are taken into use to limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault. They are also used for resistance grounding of connected generators and transformers.

Winding Resistance Meter
TRM 104
TRM104 is a portable winding resistance meter, designed to work in live EHV switchyards. Winding resistance values of large transformers up to 500 MVA and rotating machines are directly displayed. The meter is protected against the back emf offered by large inductive winding. A back-lit 4 line LCD with a user-friendly menu sets up the instrument for the test. Winding resistances and safety messages are also shown on this display. It is possible to measure the resistance of two windings simultaneously.The meter contains a special power source for rapid stabilization of test results.

Contact Resistance Test Sets
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Our range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.
