The PQ-Sensor is a uniqe device for upgrading CVT's for harmonic and Power Quality measurements. Capacitive Voltage Transformers have a very limitted frequency range. The internal LC- circuit is tuned for grid frequency. A CVT equipped with a PQ-sensor is able to transmit frequencies from 10 to 5000 Hz.
Note: For transmitting of transient signals an RC-Divider ROF is required!
