SBCT - Current Transformer - Outdoor Mounted Slip-Over Bushing CT

By Meramec 
By Meramec
The outdoor mounted slip-over bushing current transformer (BCT) is self contained and designed to be mounted externally over the high voltage terminal bushing power transformers, power circuit breakers and cable terminators (potheads). In most cases the slip-over BCT, with its ease of installation, is a reliable and economical solution when upgrading system protection and adding additional metering points. When properly installed, the slip-over 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 virtually unlimited short circuit capabilities, far surpassing its stand alone wound-type counterpart.
