Described in this guide are methods to evaluate and test the electrical performance of energy saving devices (ESDs). Measurement methods that focus on monitoring the power consumed or generated by the observed load or generator without the ESD connected into the circuit and with the ESD connected and energized into the circuit are described. Detailed protocols describe step-by-step the testing circuits, the type and accuracy of evaluation instrumentation, and the order of the test measurements. Special emphasis is given to sources of measurement errors due to incorrect connection of instrumentation, inadequate instrumentation, or incorrect interpretation of ...

It is the purpose of this guide to provide instructions for the measurement protocol of the most relevant electrical parameters such as voltage, current, kilowatts, and kilovars that are needed in determining the energy consumption of ESDs. This guide also provides guidance for measuring performance characteristics of various loads affected by the ESD, such as lumens, rotations per minute, torque, temperature, voltage, etc.
