EICR form - feeder pillar protective device

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 transformer itself?

How would the transformer be the protective device?

The NICEIC forms are based on those in Appendix 6 of 7671, which tend to be more suited for small, standard installations and therefore, perhaps, unsuitable for your situation.
I guess the important point is that you have exercised diligent oversight of your electrical system by subjecting it to a periodic inspection and unless there is some safety issue relating to the lack of LV side upstream protection, I wouldn’t be concerned about filling every empty box.

What does the N.I.C.E.I.C say?

This one is a DNO tx which part supplies a pillar for the distribution to several public EVSE points. The LV supply to it taken from fuse ways in the box that looks like a tall metal filing cabinet rear left.

I take it that your system isn’t so arranged?

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.

Alan.

Thanks Lyle. Unfortunately, I don’t think you can N/A this box. Bring back paper reports and certificates!!!

I don’t believe so, we have a Schneider RMU with the VIP300 on the primary, the secondary spouts go straight to singles onto the feeder pillar busbar…

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.
