Zera
ZERA develops, manufactures and sells devices and systems for producing, measuring, testing and calibrating electrical quantities. The focus lies in meter and instrument transformer test systems as well as e-mobility (testing of charging stations). Utilities, test laboratories and instrument transformer manufacturers are among their customers worldwide.
Founded as the “Zähler-Eich-und-Reparatur-Anstalt“(Meter-Calibration-and-Repair-Institute) in 1920, ZERA evolved from a service provider for meter calibration into a highly specialized producer of testing technology.
