Theory In electrical and electronic engineering, a clamp on ct is an electrical device with jaws which open to allow clamping around an electrical conductor. This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe. Clamp on cts are typically used to read the magnitude of alternating current (AC) and, with additional instrumentation, the phase, waveform and harmonics can also be measured. Some clamp on cts can measure currents of 100 A and more. Applications The round jaw design on the P20 AC clamp on ct along with the high content Permalloy core makes them well suited for power quality analyzer applications where high accuracy and low phase shift along with wide frequency are important. Measurement range is 1mA to 120A. It can measure the min current only 1mA, linear good for instruments. The P20 clamp on ct is a general purpose 100A AC current clamp designed for use with DMMs, loggers and other instruments that have a current input. It ha s a 1000:1 ratio and output of 1mA per amp or 1mV per amp measured in the jaw. The P20 has an integral 2.5m lead terminated. The rounded jaw design on this clamp on ct makes it well-suited for power applications where high accuracy 0.1% and low phase shift and wide frequency response are important.
