Metering Panel (MTP)
A metering panel contains a primary horizontal busbar system with a bus tap-off that drops vertically to the bottom
of the enclosure. The vertical bus is connected to voltage transformers, which can be of the fixed or withdrawable
type. Sometimes a main earth switch is supplied. Metering equipment is often contained within the segregated
low voltage compartment, located at the top-front of the enclosure.
AuCom provides a Metering Panel as part of its L-Series switchgear range. This is rated at 12 kV from
630 A to 2000 A. An IAC classification of 31.5 kA for 1 second is achieved by double skin
compartments, special locking door designs and top-exit arc flaps for pressure release.
