Transformer Winding Resistance Measurement with Raytech Winding Resistance Meters

Raytech WR50-12 Two Channel Winding Resistance Test SetTransformer winding resistance can help you determine the condition of transformers. When a transformer develops defects like coil to core or coil to coil shorts, opens and corroded connectors, the resistance of the windings change. It is a good idea to regularly test transformer components because a defect can cause severe power losses, electrical instability and eventual failure.

For Accurate Ductor Testing – Raytech Micro Centurion II Micro-Ohm Meter

Raytech Micro Centurion II MC2 200A Precision Micro Ohm MeterA contact resistance test (also known as a ductor test) measures the resistance of electrical connections such as joints, terminations and connectors. These can be connections between any two conductors, for instance busbar sections or cable connections. The test measures the resistance at the micro- or milli-ohm level and is used primarily to verify that electrical connections are made properly, and can detect the following problems:

Rent the Raytech TR-SPY Mark III for Precision Laboratory Measurements

Raytech TR-SPY Mark III Three Phase TTR (Transformer Turns Ratio)Transformers are simple devices in concept, with two coils of insulated wire wound in close proximity on an iron core (windings). One wire (primary) is connected to a power source, such as the utility or a generator. The other wire (secondary) provides power, “transformed” in some way, to the load. Energy transfer from one wire to the other is through magnetic induction.
