Project Input Collector

Inputs by Owner

Electrical ratings

Owned by the project electrical engineer

Rated capacity in kVASized on kVA, not kW. A 1000 kW load at 0.8 power factor is 1250 kVA of demand. Primary and secondary line voltageSecondary voltage also decides the regulatory classification screen. Frequency60 Hz and 50 Hz are different core designs, not a setting. Phase count Winding connection and grounding arrangementMust match the upstream system earthing and the downstream protection philosophy. Impedance targetComes from the protection study, and carries a regulatory consequence outside 5.0–7.5 %. Tap range required Basic impulse insulation level

Network arrangement

Owned by the utility or network owner

Feed arrangement: radial or loopSets the bushing count and therefore the tank. Separable connector interface: 200 A elbow or 600 A T-body Switching philosophy and switch type Upstream protection settings to coordinate against Utility accepted-equipment requirementsA unit that does not meet them will not be energised.

Site conditions

Owned by the site owner or EPC contractor

Fire code constraint and permitted insulating medium Seismic anchoring requirement Ambient temperature range and altitude Corrosion exposure and required coating class Access, working space and vehicular exposure at the pad Flood risk or submersible requirement

Test and document scope

Owned by the buyer

Routine test report format required Which tests, if any, will be witnessed Design-proven evidence required on temperature rise or short-circuit withstand Nameplate language and units Drawing set required for approval
