Engineering Overview & Scope
Manufactured using vacuum-degassed cycloaliphatic epoxy resin, Positive Power Current Transformers (CT) provide superior dielectric strength, partial discharge resistance, and high dynamic short-circuit withstand for 11kV and 33kV switchgear panels.
Key Engineering Advantages
- Vacuum cast cycloaliphatic epoxy resin providing high insulation integrity
- Dual or triple core designs for simultaneous metering and protection
- High accuracy classes (0.2S, 0.5 for metering; 5P10, 5P20 for protection)
- Superior dynamic short-time thermal current withstand
- Compact dimensions fitting standard metal-clad switchgear cubicles
Primary Industrial Applications
- ▪ 33kV & 11kV Switchgear Panels
- ▪ Substation Busbar & Feeder Protection Relays
- ▪ Utility Revenue Tariff Metering Cubicles
- ▪ Transformer Differential & Overcurrent Protection
