Date:2023/3/2 11:59:02 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,WDZ-5271 VT management relay Voltage transformer protection and measurement device
VT management relay WDZ-5271 is mainly used for monitoring and voltage protection of PT cabinet voltage transformers in 10KV, 6KV or 380V systems of power plants, and can be applied to Y/Y/open delta, Y/Y/Y type voltage transformers device protection and monitoring.
Measurement and control function of WDZ-5271 VT management relay
1.Measurement function: Provide the three-phase voltage of 2 groups of PT, the voltage before one fuse, the zero-sequence voltage, and the frequency.
2.Input: provide standard 24-way input.
3.Output: standard 20 relay outputs are provided, with 24 open contacts. 8-channel signal output.
4 .Output 4~20mA: The device provides 1 channel of 4~20mA output, and 2 channels of 4~20mA output are optional, and the corresponding measurement and multiple can be set arbitrarily.
