Product Descriptions

Recommended solution for metering and protection devices compatible with the new generation of instrument transformers. the customer has to check the installation conditions taking into account that calibration is valid for the agreed cable length and burden. the meter / relay applies via software the correction coefficents to compensate the ratio and phase errors respect to rated values.

low-power voltage output from capacitive Voltage divider and / or Rogowski coil current sensor. features: high linearity, wide dinamic range, no need of auxiliary power supply, accuracy class up to 0,5 in the operating temperature range, typical frequency bandwidth 10 kHz. limits: compatible with output cables up to 10 m, calibration of each sensor by means of correction coefficients for ratio and phase, calibration valid for the rated secondary burden.
