Power


	UK Design and manufacture of wideband current measurement transformers and wideband voltage measurement transformers

Power current transformers for 50/60Hz fundamental

and harmonics to 10KHz

These transformers are designed for use at power frequencies where accurate recording of higher order harmonics is required

Power current transformers, illustrated with and without feet.

Nominal dimensions in the table below for the different ratings.

		Current ratio accuracy +/-2% over the range 50 Hz to 10 KHz, (50:1 and 10:1 ration accuracy +/- 3% at 50 Hz, +/-2% 150Hz to 10KHz. Notes (1) Sensitivity may be reduced by employing a lower value resistor. Sensitivity = Load/Ratio. Class 1 performance at 50/60Hz 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. (3) The table above represent our most popular ratio and sizes, please contact us for other specifications not included in the table. 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.
