Electrical Calculators

Calculate estimated three-phase kW, current imbalance, and voltage imbalance from common field readings.

Three-Phase kW Calculator

Estimate three-phase electrical kW from voltage, amperage, and power factor.

Estimated kW: —

Formula used:

kW = Volts x Amps x 1.732 x Power Factor / 1000

Explanation: This calculator estimates three-phase electrical power using line voltage, amperage, and power factor. If power factor is estimated instead of measured, the calculated kW is also estimated.

Current Imbalance Calculator

Enter the three phase current readings.

Current Imbalance: —

Formula used:

% Imbalance = Maximum Deviation from Average / Average Current x 100

Explanation: This calculator averages the three phase current readings, finds the largest deviation from that average, then converts that deviation into a percentage.

Voltage Imbalance Calculator

Enter the three line-to-line voltage readings.

Voltage Imbalance: —

Formula used:

% Imbalance = Maximum Deviation from Average / Average Voltage x 100

Explanation: This calculator averages the three line-to-line voltage readings, finds the largest deviation from that average, then converts that deviation into a percentage.

Want to compare electrical readings against chiller load, kW/ton, and operating history? That requires a structured log.
