Raytech WR50-12 for Reliable Digital Winding Resistance Measurements

  • Uncategorized

Winding resistance measurements are made to check transformer windings and terminal connections. Results can be used as reference for future measurements and to calculate the load loss values.

Measuring the winding resistance is done by using DC current and is dependent on temperature. Because of this, temperatures must be measured when measuring the winding resistances and should be recorded as well.

Winding resistances are measured between all connection terminals of windings and at all tap positions. During this, winding temperature should also be appropriately measured and recorded.

The measuring current can be obtained either from a battery or from a constant (stable) current source. The measuring current value should be high enough to obtain a correct and precise measurement and small enough not to change the winding temperature.

The Raytech WR50-12 Digital Winding Resistance Meter is designed for a high degree of accuracy for the measurement of very low resistance of inductive loads.

With an easy to use operation screen, which allows quick selection of the current level to be measured, the Raytech WR50-12‘s high precision, fully automatic, multi-microprocessor based system is designed for highly accurate readings on-site with laboratory precision.
