3 Phase Water Heater Calculation

Three phase power and current the power taken by a circuit single or three phase is measured in watts w or kw.

3 phase water heater calculation.

The relationship between kva and kw is the power factor pf. Locate actual applied voltage. Multiply heater rated kw by factor shown to obtain actual kw capacity. Chromalox is a thermal technology company.

It draws appx 24 amps per phase and appx 1 amp in neutral due to little imbalance in heater. In case of star connection the neutral carry zero current acting as a return path for current. It is a three phase unit in which i have connected 4 x 1 5 kw heater across each phase to neutral. Thus having 3 x 4 x 1 5 kw 18 kw total.

In balanced three phase wiring all the hot wires lines carry equal supply same magnitude of current and voltage. Leverage watlow s growing toolkit of calculators equations reference data and more to help design your thermal system. We engineer thermal solutions for the world s toughest industrial heating applications. Locate heater rated voltage.
