Grounding Voltage Transformers ZNOL.02-27 III for 25 kV Network Applications

Transformers are designed to convert high voltage of the contact network with a nominal value of 25 kV, 50 Hz into low, galvanically isolated voltage for power supply of electric energy metering devices, to measure the voltage value of the contact network by the control system of electric locomotives and traction converters, to determine the type of current in the contact network.
