EICR form - feeder pillar protective device

Lee Petherick

Good afternoon all, it's been many years since I've posted in the IET forums, but I've had a search and cannot find the answer.

We're carrying out EICRs on our private HV network and are creating EICRs for the feeder pillars using the NICEIC software (not the best).  Would anyone have any idea what to put as the supply protective device, as the only protective device upstream of the incomer to the feeder pillar is the VIP300 relay on the HV side of the TX?

    The VIP300 is a fairly basic overcurrent &earth fault relay. This is your protective device. You will need to calculate the LV current for your relay setting, and will probably need to calculate your max fault current too. 

    Regards,

    Alan.

    1. Thanks Alan, any idea of the BS EN number for these relays, although I can almost guarantee it won’t be a choice for the NICEIC pick list? Calculating secondary current won’t be an issue.

    Or the max fault current for that matter.

    I am not aware of a British Standard for a power system protection relay. The individual characteristics such as “instantaneous” or “standard inverse” etc do all have individual British / European Standards. One solution (perhaps) is that the HV side of the transformer is specifically excluded from BS7671, so maybe you can refer to the value as a note and use n/a as LV protection doesn’t exist. 

    Regards,

    Alan.

    Thanks Alan, I will see what the NICEIC form actually allows to be input.
