Bushing-type current transformers are used wherever high currents are to be acquired and processed. They are directly placed on the primary conductor (bus bar or conductor) through the opening. The secondary side (usually a measuring device, energy meter or display) is connected by front and rear connecting terminals.
Bushing-type current transformers constitute the most reliable, precise and cost-effective current transformer versions. However, the primary conductor must be disconnected for installation purposes. For this reason, they are more suitable for new facilities.
