How does ATS48 measure the torque?

Published date: 07 March 2019

The ATS48 calculates the motor torque based on the current, because when a motor has constant voltage and frequency, the amount of torque is directly proportional to the amount of current.
Rated torque is not defined in ATS, so the torque value is only relative (referred to rated torque Tn)
This value of relative motor torque is used in function like motor underload monitoring (ULL), threshold set in LUL (underload threshold)
