Prior to installing the new cartridge verify that the kV rating and length matches the
cartridge being replaced. Failure to use the correct length integral cartridge will
result in poor electrical contact between the cartridge and Bay-O-Net housing
terminals, resulting in possible equipment damage.
For pad-mounted transformer, the load loss and no-load loss are the same for transformers
with the same capacity, which have nothing to do with the voltage rating.
