Power current transformers




	POWER CURRENT TRANSFORMERS 50/60 Hz fundamental, harmonics to 10KHz These transformers are designed for use at power frequencies where accurate recording of higher order harmonics is required

Current ratio accuracy +/-2% over the range 50 Hz to 10 kHz, (50:1 and 10:1 ratio accuracy +/-3% at 50Hz, +/-2% 150Hz to 10 kHz)

Custom designed transformers available in this range

Notes

(1) Sensitivity may be reduced by employing a lower value resistor. Sensitivity = Load/Ratio. Class 1 performance at 50/60 Hz except in models M5002001 and M5002005 which have class 3 performance.

(2) Available at the equivalent price in other currencies at prevailing exchange rate, discount for six or more

IMPORTANT:

Current transformers should not be operated with the secondary open circuit as very high terminal voltages may be present.

Operation under this condition may permanently damage a transformer and constitute a shock hazard
