Abstract

PURPOSE: To reduce the number of transformers used for investigating the trouble of grounding fault while obtaining stable output even in rainy days, by providing a single-phase current-voltage transformer with the two functions of a split-core type current transformer and a capacitor type voltage transformer.
CONSTITUTION: Voltage transforming capacitor 7 are provided in series in a handle of a split-core type current transformer. One end of these capacitors 7 is connected to a core portion 3 of the split-core type current transformer via connecting wire 5, and the other end of a connector 9, thus extracting voltage. A conductive contactor 2 which is in close contact with the core portion 3 is provided to a holding portion of a distribution line in the split-core type current transformer. Current output is extracted from a secondary coil 4 of the said current transformer. The output is guided to the connector 9 through an outgoing line 8 with the above voltage output, and extracted to the outside. Thus, the number of transformers used for investigating the trouble of grounding fault can be decreased to three.
