Outdoor 35-220kv High Voltage Current Transformer

An Outdoor 35-220kV High Voltage Current Transformer (HVCT) is a type of instrument transformer designed to measure high currents in power systems with voltages ranging from 35kV to 220kV. The HVCT works by stepping down the high current flowing through a power line to a lower, measurable level, which is proportional to the primary current.

An Outdoor 35-220kV High Voltage Current Transformer (HVCT) is a type of instrument transformer designed to measure high currents in power systems with voltages ranging from 35kV to 220kV. The HVCT works by stepping down the high current flowing through a power line to a lower, measurable level, which is proportional to the primary current.

The outdoor design of this transformer makes it suitable for use in harsh environments where it is exposed to the elements, such as wind, rain, and sunlight. The transformer typically consists of a core, primary winding, and secondary winding, which are all housed in a weather-resistant enclosure. The core is typically made of a high permeability material such as silicon steel, while the windings are made of copper or aluminum to provide low resistance and high conductivity.

The HVCT is typically connected in series with the high voltage line, and the current flowing through the line is then passed through the primary winding. The secondary winding is connected to a measuring device or relay that detects the current and sends a signal to the protective system to trip the circuit breaker in the event of a fault.

Overall, the Outdoor 35-220kV High Voltage Current Transformer is a crucial component in the protection and measurement of high voltage power systems, enabling accurate monitoring and control of electrical power.
