Buchholz Relay Transformer Wiring Diagram Control Panel - • Interfaces to different transformer types. • Up to 4 control modules in one panel. • Possibility of parallel operation of transformers. • Integration on IED networks using IEC 60870-5-103 & IEC 61850 Figure 7 – Automatic volatge regulator Medelec Switchgear Ltd Power System Protection and Control Panels 5. Buchholz Relay Photos Gas-detector relay (known as a Buchholz relay) for conservator- type transformers, generally when rated 7.5 MVA and larger. The device is mounted in the pipe between the highest part of the transformer tank. schematic/electrical parts 30010, 30015 and 30022 >>relay-pilot or control crd relay-ok to open door w7t5es+a 09c024d71 relay 4pdt difgld 14pn 240v control panel crdl relay-door closed and locked w7t5es+a 09c024d71 relay 4pdt difgld 14pn 240v control panel or -3 for voltage control panel exhv-1 transformer-208vac to 240vac w7t5elv.

the Buchholz relay is mounted on the connecting pipe between the transformer and the conservator: the arrow marked on the relay cover must point toward the oil conservator. The pipe should not contain any right-angle elbow. Pipe diameter should correspond to the diameter of the relay’s hole for the oil passage.. Wiring theHVAC system to EWC-ST-2E or EWC-ST-3E is typical of wiring a subbase to a heating/cooling system. (4 wires required.) The following terminals are on the system terminal block: R-Y-W-G-Wire to the RH heating transformer and/or the RC cooling transformer. Wire to the Compressor Relay.
