LA in pad mounted distribution transformer
LA in pad mounted distribution transformer
(OP)
hi
We are intending to replace all pole mounted transformer and over head distribution lines in a town with pad mounted transformer and underground cabling system. It will be done in a phase to phase basis . I mean like we build up underground cabling system and install new pad mounted transformers and uninstall the existing system.
Here my question is
while installing pole mounted distribution transformer, we install lightning arrester in every transformer location , but how frequently do we need to install LA (lightning arrester) in a pad mounted (kiosk type) transformer or we do not need at all except in specific place or we do install in every location of transformer.
I need the suggestion
regards

It was a trailer park where all O/H lines were tapped to new pad mounted transformers. All lateral tap had fusing (fuse cut-out with arrester). We ordered pad mounted transformers with L.A. It was a 8 kV application actually a very old system.
You can call any pad Dist XFMR manufacturer like moloney electric in Canada or Carter international in Winnipeg and they will be able to provide you some typical application input which certainly comes handy at times.
I am not sure where you are located but in Canada, ESA had input in our design and it was mandatory to do this.
