How do I calculate the carbon footprint of a voltage stabilizer?
A stabilizer is mostly its transformer: weigh the copper or aluminium winding and lamination steel per unit and multiply by supplier figures. Add the board, relays and cabinet, then winding, assembly and testing energy, divided by units passed.
Bought-in parts
- Copper or aluminium winding wire.
- CRGO or CRNO lamination steel.
- Control board, relays and a metal or plastic cabinet.
Making
- Transformer winding and varnish baking.
- Assembly and wiring.
- Testing across the input voltage range.
Per unit
Report per unit by kVA rating and winding metal, since copper and aluminium windings differ in weight and footprint.
Worked example: voltage stabilizer unit per unit (one month)
- Electricity: 20,000 kWh x 0.710 = 14,200 kg CO2
- Units produced: 8,000
- Plant total: 14,200 / 8,000 = 1.775 kg CO2 per unit
- Add winding metal, steel and cabinet for the full figure
Inputs are illustrative; use your own bills and production records.
What Senseible does here
Senseible reads the plant's electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and fuel invoices (IPCC 2006 defaults) into a fingerprinted Scope 1 and 2 record, the plant-level input to a per-unit figure. Bought-in materials go to the supplier evidence trail; product reports are self-declared drafts.
