Electrical Distribution

The intake and everything that shares it out - incomer, transformers, switchgear, standby generation, CHP, solar, storage and power factor correction. This is where a site's dependency chain starts.

12 types, and what a survey records

Equipment type	Recorded for each one
Electrical Incomer / HV Supply	Agreed supply capacity · Supply voltage · Peak demand · Annual consumption · MPAN / meter reference · Half-hourly metered · Alternative supply
Transformer	Capacity · Primary voltage · Secondary voltage · Vector group · Cooling type · Tap positions
Switchgear / Distribution	Rated voltage · Rated current · Short circuit rating · Metering fitted · Meter protocol
HV Switchgear / Ring Main Unit	Voltage · Rated current · Type · Protection relay last tested · Last maintenance / partial discharge test · SF6 filled
Standby Generator	Rating · Fuel · Fuel storage (l) and autonomy · Start arrangement · Test run regime · Last on-load test · Load it covers
CHP / Generator	Electrical capacity · Thermal capacity · Voltage / phase · Power factor · Fuel type · Fuel consumption rate · Electrical efficiency · Thermal efficiency · Overall efficiency · Heat recovery method · Engine hours · Grid export capability
Solar Inverter	Max DC voltage · MPPT voltage range · Number of MPPT channels · Rated AC power · Max AC power · Output voltage · Communication protocol · Monitoring portal
UPS	Rating · Autonomy at load · Battery type · Battery installed date · Last discharge test · Load it covers · Maintenance bypass
EV Charging	Charge points · Power per point · Type · Load management · Access · Annual consumption
Battery Energy Storage	Capacity · Power rating · Chemistry · Cycles to date · Used for · State of health · Fire protection
Wind Turbine	Rated power · Hub height · Rotor diameter · Annual generation · Capacity factor · Last scheduled service · Export
Power Factor Correction	Rating · Target power factor · Power factor achieved at the meter · Control · Capacitors last tested · Reactive charges on the bill

Anything not listed is recorded under “Other Electrical Distribution” — no list of industrial equipment is ever finished, and a register that pretends otherwise forces people to pick something untrue.
