What is the difference between a bar type CT and a window type CT?<br />

A bar type CT is an in line CT, much more costly and is mounted in line with the bus bars (bolted on both sides). The bar type CT is fully insulated to the switchgear voltage. A window type CT is rated at 600 volts and has the incoming or outgoing insulated / shielded cables pulled through it. The high voltage shielded cables are pulled through the hole or ``window`` in the middle of the CT. This type CT is much less costly than the bar type.
