Contact Resistance Tester
JYL
-
As a high current passes through a pair of mechanically independent metallic contacts, the contact resistance must be as low as possible. Increasing the contact resistance of the contact often causes a large voltage drop on the contact, which reduces the input power of the load equipment. If the contact resistance of one or two contacts becomes large, the three-phase voltage of the load equipment will be unbalanced, causing phase loss operation.

Winding Resistance Meter
TRM 25
-
SCOPE introduces 25 A state of the art precision winding resistance meter, specially designed for field testing as well as factory testing of large transformers up to 500 MVA. Winding resistance value of transformer and rotating machine are directly displayed on 5.7” TFT display. TRM 25 is designed to work in live EHV switchyard conditions, ensuring operator’s safety and repeatability of results. Maintenance time saving is ensured by one time connection to transformer with simultaneous resistance measurement of three / six windings, measurement of resistances of all taps with automated tap change and demagnetization facility. The meter is protected against the back-EMF offered by large inductive windings.
