Three-phase Current Isolation Calibration Device with ICT

Three-phase Current Isolation Calibration Device with ICT 

A Solution to Truly Achieve Non-Disconnection Calibration of Three-Phase Electricity Meters

Currently, the number of three-phase electricity meters with measurement circuits of current and voltage that cannot be disconnected (inline type) is continuously increasing in both production and application. When calibrating such three-phase electricity meters where the current and voltage measurement circuits cannot be separated, it is necessary to isolate the current and voltage circuits. For multi-position electricity meter calibration devices, a 1:1 three-phase current isolation transformer (ICT) needs to be added to each position.

The three-phase multifunctional electricity meter (ICT) calibration device launched by our company in 2007 employs a unique high-accuracy electronic compensation current transformer technology, which enables 1:1 current isolation for each meter position, thereby truly realizing the non-disconnection calibration of three-phase electricity meters.

The successful application of this technology is of great significance for obtaining various data indicators of three-phase electricity meters under actual on-site wiring conditions (non-disconnection), more realistically reproducing the error characteristics of three-phase electricity meters in actual use, and further improving the efficiency of meter calibration.

In 2007, the Beijing Electric Power Bureau’s Electricity Metering Center purchased four 0.05-class, 16-position three-phase multifunctional electricity meter calibration devices (capable of truly realizing non-disconnection calibration) through a bidding process. After nearly a year of use, all performance indicators have met or exceeded the requirements of the bidding technical documents and have been certified by relevant metrology departments. The image above shows the 0.05-class, 16-position three-phase multifunctional electricity meter calibration device (capable of truly realizing non-disconnection calibration).
