Measure Low Resistance Accurately with the Megger DLRO200-115

by Protec Tech Team January 14, 2014

One of the best methods of testing the current carrying efficiency of conductor junctions is by measuring the junction resistance. Circuit breaker or relay contacts, bus bars and switchgears constantly carry high currents. If the junctions deteriorate, the current carrying efficiency may be reduced and cause several problems like welding of contacts, localized Ohmic heating and eventual component failure.

Heavy Duty Megger DLRO10HD Digital Low Resistance Ohmmeter Combines Ruggedness and Accuracy

by Protec Tech Team December 10, 2013

An ohmmeter is an electronic device that measures electrical resistance, such as that of a circuit component. Ohmmeters come with different levels of sensitivity, some are designed to measure low-resistance materials, while others measure higher resistance.

An ohmmeter functions by passing a constant current or voltage though an object, such as voltage from a battery, and then measuring the resulting voltage with an ammeter after it passes through the resistance. The higher resistance the material has, the less current will pass through it. An ohmmeter is typically not used to measure resistance across an entire circuit, but rather through different parts of the circuit, although it can be used to test that a circuit is not broken. Components of a circuit can be removed and tested individually for resistance.

Test Resistance with Reliable Megger DLRO10HD Digital Low Resistance Ohmmeter

by Protec Tech Team October 15, 2013

It is important to measure low resistance in order to ensure that a device is still within its optimum resistance range.To measure low resistance, a digital low resistance Ohmmeter or DLRO is used.  Protective devices and relay contacts are some components often tested for resistance problems, as these components are exposed to vibration, corrosion, electrical and thermal stress. Ideally, the contact points should have a resistance of a few microOhms to ensure maximum transfer of power. When the resistance of relay or circuit breaker contacts increase due to carbon deposition, corrosion and other contaminants, the contact points may heat up during operation. This can cause further degradation of the components and lead to eventual failure.
