How this service works
Balanced three-phase kW, kVA, kVAR and line and phase current from voltage, power factor and one of current, kW or kVA.
Output
Returns a JSON object with the full set of three-phase power quantities: real power (kW), apparent power (kVA), reactive power (kVAR), power factor, line current (A), phase angle in degrees, wye phase voltage (V), delta phase current (A), kW per phase, input mode used, and a human-readable summary. Fields not computable from the given input are returned as null.
Example use cases
Motor load kVA sizing
“I have a three-phase motor running at 480 V line-to-line drawing 120 A per line — can you calculate the kW, kVA, kVAR, and power factor angle for that load?”
Generator sizing from kW load
“We have a 3-phase, 230 V balanced load consuming 50 kW at a power factor of 0.9 — what kVA rating do I need for the generator and what's the reactive power?”
Panel current from kVA rating
“I've got a three-phase 415 V distribution panel rated at 250 kVA — what's the full-load line current and how much reactive power kVAR does that represent at unity power factor?”
Technical details
Endpoint
GEThttps://electrical-calc.x402tookit.com/three-phase-power?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a complete set of three-phase AC power quantities (kW, kVA, kVAR, line current, phase angle) from a known voltage and any one of current, kW, or kVA. Ideal for electrical engineers sizing generators, switchgear, transformers, or cables for balanced three-phase industrial loads. Prefer this over manual calculation or generic math tools when you need all derived quantities in a single call with consistent units and named fields.
Side effects
- Missing required voltageV parameter returns a validation error
- Providing more than one of currentA, kw, or kva results in ambiguous input error
- Power factor outside (0, 1] range causes a validation failure
- Zero or negative voltage value rejected as invalid
- Providing none of currentA, kw, or kva results in insufficient input error
