OBCT - Current Transformer - Internally Mounted Oil-Type Bushing CT

Oil-type bushing current transformers are designed to be mounted inside the tank of a power XFMR along bushing shank or in power circuit breakers or voltage regulators. Its construction provides a low leakage product with extremely high short circuit capabilities. Oil-type BCTs can be used on higher system voltage levels while maintaining its own 600 Volt class rating.

• Each unit is customed engineered to fit over any bushing shank
• Designs can be engineered to match existing CT charateristics
• Primary currents greater than 8,000 Amps.
• Gapped cores for remanence control and transient response
• Air core linear couplers
• Rating Factors: Up to 2.0 @95°C Ambient
• Metering class: 0.15S thru 2.4 / 0.2S thru 5.0
• Burdens: B0.1 thru B1.8 / 2.5 - 45 VA
• Available in a variety of winding arrangements, Single Ratio (SR), Dual Ratio (DR) or Multi Ratio (MR)
• NOTE: Sizes and accuracy class are dependent on current ratio.
