WebFeb 3, 2024 · How do you read a Megger? If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes. Any reading above 1.25 is considered excellent. WebThe TTR100-1 measures the highest turns ratio in the industry with an accuracy of 0.2 % or better and with the lowest excitation voltage. It can also accurately measure phase deviation (in minutes or centiradians) of the transformer primary versus secondary. This measurement is also useful in verifying phase errors in PTs and CTs.
