Current Measuring Transformers ASR, ASK, WSK
Current Measuring transformers ASR, ASK, WSK measure AC currents and are designed to convert high current into lower current value. The secondary current is 5A, rated frequency from 50 Hz to 60 Hz. The accuracy class is 1.
Current Measuring Transformers
Primary current: from 30A to 7.500A
Secondary current: 5A
Accuracy class: 0.5, 1.0, 3
Transformers are used for cables and busbar.
