1 Scope

This standard applies to large motors, is a supplement to IEC 60034-2-1. This standard specifies the test method to determine the efficiency and access to various losses, these methods are applicable to full load test can not be implemented, the test The result is a high degree of uncertainty. Note. Field tests based on calorimetry at full load are accepted. This standard specifies the specific method is. --- Calibration motor method; --- since deceleration method; Calorimetry
