Recently, entrusted by the KEMA laboratory, the high-voltage metering equipment verification device independently developed by WISDOM completed the calibration at the VSL Netherlands Metrology Institute and obtained a calibration certificate. KEMA Laboratories will work with WISDOM to study and formulate the test specifications for high voltage gauges, and to test and certify high voltage gauges.

The calibration was hosted over by Ernest, a senior metrologist from the Netherlands Metrology Institute. Within two weeks, the accuracy of the high-voltage verification device was tested under different test conditions such as voltage, current, phase angle and frequency. In the four test verifications, WISDOM equipment maintained extremely high accuracy and was highly recognized by the Netherlands Metrology Institute.

The Netherlands Metrology Institute (VSL) is a certification body designated by the Dutch government to be responsible for formulating and managing national testing standards. It has a high reputation in Europe and the world. The test report or calibration certificate issued by VSL has international authority. It has the widest recognition and credibility in the world.

The acquisition of the calibration certificate fully proves the recognition of the international authoritative testing organization for our high-voltage metering equipment verification device, and also proves WISDOM"s leading position in the world in high-voltage testing technology, creating favorable conditions for WISDOM high-voltage metering products to enter the international market.
