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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Yorba Linda, CA. B&K Precision has announced its first series of DC resistance meters, models 2840 and 2841, designed to accurately measure resistance in the milliohm range. The 2840 model’s mea ...
