380V electric heating
Thread Content
For a 120Kw 380v electric heater, the current measured in delta connection is 660A. Is it possible to switch to star connection? Please explain, experts
For ordinary motors, it is possible to change their wiring configuration, and the motor’s insulation can be checked.
How can a heater with 120 kilowatts of power, 380V voltage, and a delta connection generate a current of 660A? According to the calculations, the line current is 182A. It can be changed to a star connection, with the phase current also being 182A.
It makes no sense to change the wiring to a star configuration for electric heating, right? There’s already the starting current of the motor that can cause the equipment to trip; I don’t understand why it’s necessary to make such a change. Please advise
It is generally not wired in this way; first, one must consider the power density of the electric heating wire, as well as the heat generation generated by the processing equipment under the worst operating conditions. At the same time, the UOP or IFP process packages explicitly require angular wiring.

It’s possible, but it doesn’t really make much sense, my friend
