LOAD CORRECTING CIRCUIT AND TRANSFORMER FOR CAPACITOR TYPE INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a load correcting circuit which is practically adaptive to load variation, and to provide a transformer for capacitor type instrument having the load correcting circuit.

SOLUTION: The load correcting circuit 10 for correcting load characteristics of the transformer for capacitor type instrument comprises a short-circuit guaranteeing resistance RCS, an open-circuit guaranteeing resistance RCOconnected to the short-circuit guaranteeing resistance RCSin series, and a variable resistance RCMfor load adjustment connected to the open-circuit guaranteeing resistance RCOin parallel. Here, the load correcting circuit 10 further includes a variable capacitor XCfor power-factor adjustment connected to the open-circuit guaranteeing resistance RCOand variable resistance RCMfor load adjustment in parallel, so that power-factor characteristics of the transformer for capacitor type instrument can be corrected.
