Advanced Three-phase Energy Meter Calibration Technology with Electronic Compensation

A True Solution for No-disconnect Calibration of Three-phase Energy Meters Currently, the number of in-line energy meters with inseparable current and voltage measurement circuits is continuously increasing in production and application. When testing three-phase energy meters with inseparable current and voltage measurement circuits, it is necessary to isolate the current and voltage circuits. For multi-meter calibration devices, a 1:1 three-phase current isolation transformer (ICT) needs to be added at each meter position. Our company launched a three-phase multifunctional energy meter (ICT) calibration device in 2007, which adopts a unique high-accuracy electronic compensation current transformer technology. This technology enables a 1:1 isolation of current at each meter position, truly achieving no-disconnect calibration of three-phase energy meters. The successful application of this technology has profound significance for obtaining various data indicators of three-phase energy meters under actual wiring conditions in the field (no-disconnect), more truly reproducing the error characteristics of three-phase energy meters under actual use, and further improving the efficiency of meter calibration.

Product Details

In 2007, Beijing Power Supply Bureau's Energy Metering Center purchased four three-phase 16-meter positions 0.05 class multifunctional energy meter calibration devices (capable of truly realizing no-disconnect verification) through a bidding process. After nearly a year of use, all indicators met or exceeded the requirements of the bidding technical documents and passed the assessment certification of the relevant metrological departments. The above picture shows the three-phase 16-meter position 0.05 class multifunctional energy meter calibration device (capable of truly realizing no-disconnect verification).
