Hello - new to this forum and would appreciate any help on thie NEV problem. Heres the scoop - I am working for an electric utility trying to resolve a shock complaint at a pool in a newer residential neighborhood. Suffice to say that all utility and customer equipment has been checked and all is ok. We installed a neutral blocker in the padmount transformer and it did not reduce the NEV. The transf feeds 3 other homes. A cable and phone pedestal is located at the utility transformer, we ensured that their grounds went to the primary ground only. The problem I believe lies in the fact that the CATV is grounded at each customer's service and that in a roundabout way bypasses the neutral blocker.
Is there a "blocker" for catv that can be used either at the customer service entrance or at the catv pedestal that would eliminate the ground loop during steady state conditions yet conduct during a fault or lightning?
Thanks
