Current Sensor in MV Applications
27 March 2013 | Slide 6
Rated Ratio 250A/150mv or 180 mV for 50/60 Hz
Rated burden 10 MΩ
6-24 kV AIS, up to 1250 A
Accuracy class 0.5/5P630 (KEVCD A)
Small size and low weight
Extremely low power consumption
Minimize sources of partial discharge
No saturation of current sensor
Secondary circuit of current sensor could be left opened – no risk of high voltage on secondary terminals, great for IEDs
KEMA certified as per IEC 60044-8

Voltage Sensor in MV Applications
27 March 2013 | Slide 7
Rated Ratio 1:10,000
Rated burden 10 MΩ
6-24 kV AIS
Rated voltage factor : 1.9/8hours
Accuracy class 1/3P (KEVA 24A1) or 0.5/3P (KEVA 24A2)
Small size and low weight
Extremely low power consumption
Minimize sources of partial discharge
No risk of Ferro-resonance
Secondary circuit of voltage sensor can be left shorted – no risk of explosions, great for IEDs
