Transformer monitoring apparatus
A transformer monitor includes a housing and at least two connectors. The housing has a first end and a second end opposite the first end. A first connector is positioned proximate the housing's first end and configured for connection to a first cable assembly that outputs signals representative of a primary input current to the transformer. A second connector is positioned proximate the housing's second end and configured for connection to a second cable assembly that outputs signals representative of a secondary output current of the transformer. The connectors are oriented such that the first cable assembly extends away from the housing's first end in a first direction when the cable assembly is connected to the first connector and the second cable assembly extends away from the housing's second end in a second direction generally opposite to the first direction when the cable assembly is connected to the second connector.
