Busduct Monitoring - how?
Busduct Monitoring - how?
(OP)
I work at manufacturing facility that has a busduct distribution system overhead. Each bus duct is rated for 1600 Amps (main bus) and has about 6-8 "side busses" branching off the main bus rated at 600A each. Each side bus is protected by 600a fuses. Headers are plugged anywhere along the side busses to feed the machines and equipment below.
Our problem is we have no idea on the actual loading of these side busses other than a breaker in the substation that reads the total busduct load. I have looked at putting in CT and a metering system but the bus bars are to close together to install CT's. Any ideas?? Do I have to go to a specaility shop and make some custom bus sections that can fit the CT's?

Scottyuk, I checked the website for rogowski, I think this maybe be something we can use. I am looking into seing if the CT inputs can be used on our existing monitoring system.

If this is for a metering system rather than a protection system, I think Ro-Coil have built current sourcing amplifiers to drive inputs intended for CTs in other applications. The man to speak to is called David Ward. He is an absolute mine of information and very forthcoming with assistance.
