In response of requests by our customers, the XRW1-3 Mains Decoupling Relay was implemented into the High Tech Line as a new type of device with a “special time undervoltage characteristic according to e.on and VDN*”.
The recording capacity of the disturbance recorder was extended to 20 seconds as to also allow recording of voltage time curves for a period that is typically used for the Spanish Wind Power Plant business. (REE** characteristic)
