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 equipment, motors and other equipment in the line when the line fails.
So the capacity of voltage transformers is very small, generally only a few volt-amps, tens of volt-amps, and the maximum does not exceed 1,000 volt-amps.
