Hi Guys,
We are completing a periodic inspection of a factory unit and have come across a transformer supplied from 1 of the DB's which in turn supplies 110v to a single phase DB which feeds 3 110v socket banks from D type DP mcb's.
We have been informed by NICEIC to test supply into transformer as a distribution circuit and test the 110v as a Db: Question is How do you perform zs test and will a megger MFT1552 perform a 110v zs test?
