The Megger DLRO200-115 measures contact resistance in high voltage circuit breakers, disconnecting switches ( isolators) , busbar joints, or for any other low resistance measurement.

This test set accurately measures resistances ranging from 0.1µ © to 1© , at high currents.

A versatile instrument, it can provide test currents from 10 amps up to 200 amps, subject to the load resistance and supply voltage. For those applications that demand a smooth dc current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 amps through a total current loop resistance of 11 milliohms. The filtered output of the DLRO200-115 also eliminates magnetic transients that could inductively trip a breaker’ s control ( bus differential relay) , if left in the test circuit.

The unique design allows the weight and size of the DLRO200-115 to be kept to a minimum; the instrument weighs less than 32 lbs. ( 15 kg) . This small size plus a water/ dust ingress rating of IP54 makes the test set equally at home in the workshop, on the production floor or in the field.
