The standard DL/T 846.4-2016, published on January 1, 2016, replaces the previous version DL/T846.4—2004 and provides technical specifications for pulse current method partial discharge measuring instruments within high voltage testing equipment in the power industry.
This standard offers detailed guidelines to ensure that measurement devices used for assessing insulation conditions are accurate and reliable, focusing on the application of pulsed current techniques to detect partial discharges in electrical apparatus. It covers requirements such as technical performance indicators, test methods, quality control procedures, and safety measures essential for the design, manufacture, use, and maintenance of these measuring instruments.
The standard aims at improving the accuracy and consistency of measurement results obtained through pulsed current methods, contributing to enhanced safety standards and operational efficiency in power systems. It is an important reference for manufacturers, engineers, and technicians involved with high voltage testing equipment used across various sectors including but not limited to electrical utilities, manufacturing plants, research institutions, and regulatory agencies.
