Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure. Padmount transformers are used with undergroundelectric power distributionlines atservice drops, to step down the primaryvoltageon the line to the lower secondary voltage supplied to utility customers.
Pad-mounted transformers are made in power ratings from around 75 to around 5000kVAand often include built-in fuses and switches. Primary power cables areconnected with elbow connectors, which can be operated when energized using ahot stickand allows for flexibility in repair and maintenance.
Figures
You know the components that make up a conventional substation: a transformer and a separate set of
switchgear or cut-out fuses with disconnector.
Just think about it: the total costs incurred by buying a transformer and switchgear separately—including
warehousing, transporting, installing, maintaining and retiring—far outweigh any “deal” you think you might be getting at the time of their purchase.
Sure, a transformer and separate switchgear might be the conventional solution to power distribution… but if you thinkit’s the cost-effective solution, better think again.
