Use of Current sensors for the protection of 6.6kV feeders

Use of Current sensors for the protection of 6.6kV feeders

Use of Current sensors for the protection of 6.6kV feeders

(OP)
One of the reputed vendor is giving current sensors in the 6.6kV switchgear for protection, which they are supplying to one of our projects. They say these current sensors are suitable for their protection relay and it is better than conventional current transformers (CTs).

Any insight?

RE: Use of Current sensors for the protection of 6.6kV feeders

What kind of sensor is it? There are a lot of different technologies. Some are more reliable than others.

With that said, it's darn hard to beat the reliability of core steel and copper. The one advantage of some sensor technologies is that they don't saturate/have a linear response through the fault current.

Thanks

Are these current sensors time tested or the vendor is doing an experiment at the expense of a client?

If you want an good answer, you've got to give a little detail as I requested.
