A low-voltage distribution rack (Rak TR) in Indonesia's PLN network receives power from a local transformer and distributes it to feeder lines serving residential and commercial customers. The rack's rated current capacity, its channel count, and how many channels are currently loaded are the three operational parameters that determine whether additional connections can be made and what maintenance priority the rack carries. None of that is available without structured asset records.
Asset Identity and Specification
Gardu identifies the gardu distribusi — the distribution substation that the rack belongs to. No Trafo links the rack to its specific transformer. These two fields create the positional context: which transformer, at which substation, is this rack connected to. In a utility network with hundreds of gardu distribusi across a service territory, the relationship between rack and transformer is the physical hierarchy that maintenance routing and load management depend on.
No Rak TR is the rack's physical identifier within the gardu. No Seri is the manufacturer's serial number — the identifier that links the asset to the procurement record, the warranty, and any manufacturer service history. Merk (brand) and Tipe (type) document the equipment model. In a mixed-fleet network where multiple brands and vintages of distribution equipment are in service, the brand and type fields inform which spare parts are compatible and which maintenance procedures apply.
Electrical Capacity and Loading
Rating (A) is the rack's current capacity in amperes — the maximum continuous load the rack's busbars, cables, and protective devices are rated for. Kapasitas Jurusan is the total number of feeder channels the rack provides. Jurusan Terpakai is the number of channels currently in use.
The gap between total capacity and used capacity is the available capacity — the headroom for new connections before the rack requires expansion or a new rack installation. A rack showing 12 channels with 11 occupied is essentially at capacity; a rack showing 12 channels with 6 occupied has headroom to accommodate planned new customer connections without capital investment.
The current rating against the actual loading also determines the rack's maintenance urgency. A rack operating at 95% of rated current continuously is at risk of thermal issues. Tracking Kondisi (physical condition) alongside the electrical loading parameters creates the combined picture that should drive maintenance prioritization.
Field Record and Evidence
Photo 1 and Photo 2 provide the photographic evidence of the rack's physical state at the time of inspection. For a utility asset that may be inspected once or twice a year, the photographs create the condition baseline that subsequent inspections compare against — detecting corrosion progression, cable deterioration, or busbar damage that develops between inspections.
Petugas 1 and Petugas 2 are the field technicians who conducted the inspection. Two technician names reflect the two-person safety requirement for work on energized distribution equipment. Their identification attached to the inspection record creates the accountability chain if the inspection findings or the condition assessment are later questioned.
