The grounded point of a cable shield[or screen] could be :
1)at the supply side-usually is not necessary since the
supply side is enclosed
2)at the far end-is better for receiver security.
3)if the built-up voltage-due to induction produced from
the current flowing in the main conductor-is elevated [more
than 25 V usually limited]then a middle point grounded will
reduce this voltage to a half.
4)Both ends-if the middle point it will not reduce enough
the built-up voltage.
However, the circulating current will produce a
supplementary heating of the main conductor and then a
derating factor should be introduced.
There are also other means to overcome this by cross-
bonding the shield and even the main conductor, also.

In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
