MEASURING CURRENT ON UG CABLES & IN PADMOUNT ENCLOSURES
Secondary voltage cables are generally unshielded and current can be easily measured by
placing the HVA completely over the secondary cable or cable bundle so that all cables are
completely inside the U on the HVA.
Primary voltage cables are generally shielded and the HVA cannot measure current on
a shielded cable except in areas where the shield has been removed. Current can be
measured where primary voltage cables are terminated, generally in a vault or padmount
enclosure, as long as the HVA is placed on the cable just above the termination where the
shield wires have been terminated. The HVA can be placed over small drain wires but the
cable shield wires should not go inside the U of the HVA.
