Scope

Instruction for the testing of distribution transformers as sources of voice-frequency noise for communication circuits is provided. The tests measure the degree to which a transformer may contribute to electrical noise in communication circuits that are physically paralleling the power-supply circuits feeding the transformer. They provide a standard method for use by the transformer manufacturer,...
