The item in question is the FNIRSI HRM-10 Internal resistance meter, which we show here being reviewed by [JohnAudioTech]. So what does it do, and why would you want one? The device is designed to ...

Megohmmeters (meggers) are electrical meters used to check the resistance and condition of the motor windings and the condition of the refrigeration and oil environment around the motor windings. A ...

Below are a few common questions related to winding resistance testing in power transformers: Is it necessary to use a dedicated transformer ohmmeter to make accurate winding resistance ...

This is done to verify the integrity of the insulating material, be it wire and cable insulation or motor/generator winding insulation ... which is a portable instrument that's essentially a ...

Matz Ohlen and Peter Werelius of Megger discuss the unique method of winding resistance measurements in transformers and how they are a fundamental importance to detecting potential mechanical and ...

Stepper motors contain coil windings that require resistance measurements. Measuring resistance in a production environment often requires some special circuits that minimize errors. Resistance is ...

For making these measurements, I chose the Fluke 1625 earth resistance meter, seen in Fig. 2. It is a versatile device and can do ground measurements with either the ground rod only or with the ground ...

A company named LEM introduces its Model LK60 clamp-on leakage-current meter for non-invasive checks of insulation resistance. Leakage current measurement can be used to assess the state of electrical ...

Fiberglass conduit is a wise choice for harsh, challenging environments because of its epoxy chemical resistance. This is due in part to its unique fabrication processes. Fiberglass conduit is created ...
