Description
The divider is capacitive and consists of a gas-insulated capacitor and an air capacitor with an electronic unit. The maximum voltage is determined by the gas-insulated reference capacitor the divider works with. Voltage transformers are calibrated by the differential method. Voltage transformers up to 1000 V are tested directly.
