APPLICATION & DUTY
Where JP fits
JP is an outdoor distribution cabinet associated with a distribution transformer. It brings together metering, outgoing distribution and reactive-power compensation as required by the selected scheme. Transformer capacity, feeder duties and installation conditions determine the final cabinet arrangement.
APPLICATION / 02
Rural and neighbourhood networks
For grouped outgoing supplies requiring metering and configured protection or compensation functions.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
Integrated functional arrangement
Metering, outgoing switching and compensation functions are coordinated in one cabinet. Each function should be explicitly included in the circuit schedule.
DETAIL / 02
Outdoor enclosure construction
The described enclosure includes weather-oriented door seals, a rain cover and cable-entry provisions. Material and construction options should be specified for the installation exposure.
DETAIL / 03
Metering access
A dedicated metering arrangement allows the metering equipment and its access provisions to be coordinated with the supply authority’s requirements.
DETAIL / 04
Configured protective functions
Overload, short-circuit and residual-current functions depend on the devices selected for the outgoing circuits. They should not be assumed to be identical on every cabinet.
