LVQB is a gas-insulated high voltage current transformer based on a top-core design, able to withstand current up to 4,000 A and designed for voltages from 40.5 to 550 kV. Primary and secondary windings are located inside the upper part of the transformer. Some important features of the product are:
Suitable for both metering and protection
Short primary conductor with low thermal losses suitable for high rated current
Magnetic cores made of laminated steel with oriented grain and a high level of permeability
Windings made of electrolytic copper
Safety margin for normal wind loads, stress from conductors and seismic forces
Remote control of the internal insulation level by means of pressure gauge provided with an alarm threshold and lock threshold
A pressure relief device protects the apparatus from internal overpressure
