METHOD FOR CONTROL OF DIELECTRIC CHARACTERISTICS OF INNER INSULATION OF CAPACITOR TYPE INPUTS OF POWER TRANSFORMERS AND MEASURING CURRENT TRANSFORMERS UNDER WORKING VOLTAGE

摘要

Method for control of dielectric characteristics of inner insulation of capacitor type inputs of power transformers and measuring current transformers under working voltage at which one measures load and coefficient of power of load of measuring voltage transformer connected to the same phase of system of buses with object under control, at absence of defect and at control, one calculates errors in voltage and angular one, with compensation of those one determines phase voltage of object of control and result of indirect measurements of power of losses, with remembering value of working phase voltage at absence of defect, with multiplication of result of indirect measurements of lower losses in insulation of object under control at each control by square of ratio of working phase voltages at absence of defect and at control.
