Property Specification
Type: High-Voltage Top-Core Gas-Insulated Current Transformer (40.5 kV to 550 kV)
Features: Engineered around an adaptable top-core configuration with gas insulation, this high-voltage transformer supports nominal operating currents up to 4000 A across standard voltage classes from 40.5 kV to 550 kV. Both primary and secondary windings are housed within the top enclosure. Key design highlights include a shortened primary path to minimize thermal losses at elevated load currents, high-permeability grain-oriented steel laminations, and pure electrolytic copper windings. Built to withstand environmental stresses such as wind shear, terminal tension, and seismic conditions,
Applications: Tariff and utility revenue measurement, transmission protection schemes and protective relaying, and supervisory grid control, telemetry, and power flow monitoring.
