电压互感器二次线电压降补偿器的研制

A STUDY ON THE COMPENSATOR FOR VOLTAGE DROP IN THE BETWEEN THE SECONDARY-WIRING OF A VOLTAGE TRANSFORMER

电压互感器至电能计量仪表之间二次线上的电压降，对计量精度有重要影响。笔者所研制的电压互感器二次线电压降补偿器，为解决这一问题提供了一种有效方法。文中详细介绍了该补偿装置的基本原理、特点以及提高其可靠性的措施。该装置已投产，经实际应用，收到了满意的效果。

The voltage drop in the secondary wiring connecting the meters with the voltage transformer affects seriously the accuracy of measurement.A voltage-drop compensator developped by the author provides an effective measure in solving this prablem.The paper presents the principle,special feature of the compensator as well as the measures taken for its reliability.The compensator has been put into production.The practice to use results in a sufficient effect.
