Standard 222-2025 -- Standard Method of Test for Electrical Power Drive Systems
Full Description ASHRAE Standard 222 is a method of test for determining the performance of HVAC&R-related adjustable-speed electric alternating-current power drive systems, which include a complete drive module and a motor. The complete drive module is a semiconductor power converter with means for the control, protection, monitoring, and measurement of motors. Complete drive modules are fully integrated in the motor casing, directly attached to the motor, or mounted remotely from the motor with connecting cables. The standard is intended for rating the energy efficiency and electrical compatibility of the power drive systems with the power grid and with motor insulation. |
