Digital Low Resistance Ohmmeters Manufacturers

Digital Low Resistance Ohmmeters measures resistance by measuring the amount of voltage drop across an unknown resistance. It generally exhibits an accuracy of about ±1%. In generators or motors, when breakage or distortion of damper bars occurs due to over speed or abnormal thermal gradients between bars and the connecting end rings, it causes difficulty to observe in machines that have operated in contaminated conditions and usually occur near the end ring or at the end of the pole piece. This can be detected by low resistance measurements between bars and end ring by means of digital low resistance ohmmeter.
