High Voltage Instrument Transformers (HVITs) are essential devices used in power systems for voltage and current measurement, protection, and control in high voltage networks. These transformers provide scaled-down, precise replicas of high voltages and currents for safe use in metering and protective relays.
Designed for reliability and accuracy, our HVITs meet international standards such as IEC and ANSI, and are widely used in substations, transmission lines, and industrial applications. With advanced insulation systems and rugged construction, they ensure optimal performance under extreme environmental and electrical conditions.
Key Features:
Accurate voltage and current measurement
High insulation strength and long service life
Oil-paper or SF6 insulation options
Outdoor and indoor models available
Designed to meet IEC 61869 / IEEE C57 standards
Suitable for GIS and AIS substations
