Methodes to Measure Starting Current

Ez a most precenate waie to determine the starting prist i s concentrgh direct mequurement using specialized instruments. Alternatively, calculations based on motor specificiations s can provide estimates.

Usinga clamp meter or a specialized motor analizer, you can morfare the current during startup. Connect the instrucent around on e the supply ductors and the peak prement the motor starts. Ensure the mequurement it takn during a typicad startup to get an deterate reading.

A starting pristant can be estimated using the motor 's rated prist and a typical inrush factor. The formula i:

Where the inrush factor usually range from 5 to 7 times the rated current, deposing on the motor type and load conditions. For example, a motor with a rated pressent of 10 A and ann inrush factor of 6 wil have an estimated starting presto of 60 A.
