Abstract

The high-voltage direct current (DC) technology is widely used in electrophysical, environmental, electrical, power plants and systems. Power transmission DC is more economical than on alternating current, therefore high DC lines are built in many countries. The high-voltage DC is used for testing of the insulation of capacitors, cables, rotating machines, etc. For these types of insulation, the detection of significant defects is effective at high direct voltage. The National high-voltage DC standard of Ukraine has already undergone several modernizations to improve its metrological characteristics and reliability during operation from 1999. Research of the metrological characteristics of the this standard allows to increase the accuracy and reliability of calibration of high-voltage DC working standards of accredited calibration laboratories.
