PT526 Residual voltage transformer Electrical Specification (Customized is available) Input voltage 290V Dielectric Withstanding Voltage(Hi-pot) 2500Vrms Output Voltage（mV） ≥800 mV The purpose of voltage transformers to convert voltage is mainly to supply power to measuring instruments and relay protection devices, to measure the voltage, power and electrical energy of the line, or to protect valuable…
PT531 Potentail voltage transformer Electrical Specification (Customized is available) Rated Current 30A DC Resistance at 25℃ 145±10%Ω Dielectric Withstanding Voltage(Hi-pot) 2500Vrms Inductance △I≤0.05mA No short circuit is allowed on the secondary side of the voltage transformer. Since the internal impedance of the voltage transformer is very small, if the secondary circuit is short-circuited, a large…
PT519 Potential voltage transformer Electrical Specification (Customized is available) Rated Current 30A DC Resistance at 25℃ 77±5Ω Dielectric Withstanding Voltage(Hi-pot) 2500Vrms Inductance △I≤0.05mA △I= W1-W2 The basic structure of the voltage transformer is very similar to that of the transformer. It also has two windings, one is called the primary winding and the other is…
