MLR10 Megger Leakage Reactance Tester

PublishTime：2021-11-08

● The Megger Leakage Reactor Tester MLR10 is used to measure leakage reactance and other associated parameters in high voltage power transformers. Leakage reactance, or more generally leakage impedance, is measured at the transformer primary winding while the secondary winding is shorted. Ideally, a transformer’s primary and secondary windings should be 100% coupled by magnetic flux, but in real transformers there is always a small amount of leakage flux. Leakage inductance is a result of this leakage flux.
● The amount of leakage flux a transformer has is partially dependent on the configuration of the windings. Since leakage reactance depends on leakage flux, measuring a transformer’s leakage reactance can give an indication of the condition of the windings. Changes in the leakage flux, and therefore the leakage reactance, are generally caused by winding mechanical deformation. The mechanical deformation can occur during shipping, installation, or a high current event while the transformer is in operation. Such changes can be detected by comparing before and after leakage reactance measurement values.
■ Measures the short circuit impedance of transformers
■ Useful in detecting and diagnosing winding deformation
■ Capable of performing measurements in single- or three-phase transformers
■ Optional capacitor bank testing (without the need to disconnect terminals)
