Electronic Voltage Transformer EGIW x64.
The EGIW x64 system consists of up to nine voltage sensors, transmitter and receiver electronics. The voltage sensor transforms the primary voltage Up to a low voltage, which is digitized inside the electronics and transmitted to the receiver via an optical transmission path. On the secondary side, the received optical data is converted to an analog voltage corresponding to the high voltage on the primary side divided by the rated transformation ratio. Due to the optical transmission, a high galvanic isolation is achieved between the primary and secondary side. It makes the system highly resistant against heavy electromagnetic interference and disturbance. Auxiliary power upplies (Ua) are required to run the transmitter and receiver electronics. The system includes a monitoring function, which detects power supply as well as data transmission failures and out-of-range measurements. In those cases, the error is indicated by relay status and LEDs. Conforms to standard IEC 61869-6 / IEC 60044-7
