Oil Type Current Transformer
Our Oil - Type Bushing Current Transformers (OBCT) are custom - designed to measure primary currents within power transformers. Immersed in oil, these transformers ensure accurate, current measurement and insulation, adhering to various international standards and specifications covering IEEE, IEC, CAN, BS, NBR, AS, JEC or GOST standards
- Primary currents: 50 up to 40000 Amps
- Secondary current: 1 & 5 Amps
- Frequency: 50 an d 60 Hz
- Rating Factors: Up to RF 4.0 @ 55°C Safety Factors: 5, 10
- Relaying class: Up to C800 (IEEE) / 5P20 - 200VA (IEC)
- Metering class: Exceeds 0.15S (IEEE) / 0.1 thru 5.0 (IEC)
- Burdens: B0.1 thru B8.0 / 5 – 200 VA
- Single Ratio (SR) or Multi Ratio (MR) is available
- NOTE: Sizes and accuracy class depend on the current ratio.
