Voltage transformers NKF, ZNOM, NAMI, NTMI, ETN, NOG, NKG

NKF voltage transformers - single-phase, electromagnetic, oil, three-winding, outdoor installation, are designed for large-scale conversion of AC voltage for the purpose of its further measurement and supply to the inputs of measuring equipment, protection and alarm devices. The transformers are intended for use in electrical circuits with a frequency of 50 Hz with a rated voltage up to 330 kV inclusive. Transformers designed to operate in networks with an effectively grounded neutral can withstand an excess of the primary voltage up to 150% of their nominal value for 30 s. Voltage transformers of the NKFA series. Measuring voltage transformers of the NKFA series - single-phase, electromagnetic, oil, four-winding, anti-resonance, outdoor installation, are designed for large-scale conversion of AC voltage with a frequency of 50 Hz or 60 Hz for the purpose of its further measurement and supply to the inputs of measuring equipment, protection and alarm devices ... Voltage transformers of the NKFA series are manufactured for voltage classes from 110 kV to 500 kV inclusive.
