Wound Ring Type Low Voltage Protection Devices DC Contactor PR Current Transformers

PR Current Transformers

Current transformer for protection requires the current to run in the circuit that carres many times of rated current, it is better than the current transformer for measurement that is restricted by many conditions. When a current transformer provides the current for the protection relay, it must guarantee its characteristics ratio reaches some multiple of rated current value. This multiple may be5, 10.20 or more, this is so called accuracy limit factor. Therefore, when selecting the current transformer for protection, as for its accuracy and accuracy limit factor, user shall make the careful examination in the features of relay and ciruit conditions,hereinto, so-called circuit conditions include the relay load and conductor load.
