Application for Compressor testing
Testing the compressor performance can be done in two ways: statically or dynamically.
In both cases, in order to get the data of the compressor output torque, it is necessary to use one the following two options:
Compressor manufacturers and driver manufacturers are both interested in the static and dynamic performances of the compressor.
The dynamic performances include the compressor’s torque, speed, voltage, current, and power, during the acceleration of the compressor.
For the dynamic performances, MEA uses its (has developed) unique, worldwide patented, Inertial Dynamometer System capabilities.
The testing includes:
For the static performances, MEA uses its four-quadrant regenerative load dynamometer system capabilities, that allow loading and rotating the CUT (Compressor Under Test) clockwise and counterclockwise.
