Models PT W3-1-60 & PT W3-2-60 (a) Two fuse transformers should not be used for Y connections. It is preferred practice to connect one lead from each voltage transformer directly to the neutral terminal, using a fuse in the lline side of the primary only. By using this connection a transformer can never be made “live” from the line side by reason of a blown fuse in the neutral side. For continuous operation the transformer primary voltage should not exceed 110% of rated value. (b) Voltage transformers connected line-to-ground cannot be considered to be grounding transformers and must not be...
