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

By Meramec 
By Meramec
The internally mounted oil-type bushing current transformer (BCT) is designed to be mounted along the ground collar of a high voltage bushing shank, inside the tank of a power transformer, power circuit breaker or voltage regulator. When properly installed, the oil-type BCT can be used on higher system voltage levels while maintaining its own mere 600 Volt class rating. Its simple construction provides a low leakage product with extremely high short circuit capabilities.
  • 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.
