Máy đo tỉ số máy biến áp Chauvin AEMC DTR Model 8510
Cat. #2136.50
Primary to secondary turns ratio, Polarity, Excitation current, Automatic self-calibration
Digital transformer ratiometer for on-site testing of power, potential, and current transformers. Measures primary to secondary turns ratio, polarity, and excitation current. Automatically self-calibrates and checks for open windings/connections/circuit breakers, short circuits (excess excitation current), incorrect test lead placement, and reverse polarity.
