IEEE Guide for Evaluating and Testing the Electrical Performance of Energy Saving Devices

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 results. Contained in Annex B are practical examples and explanations of the physical mechanisms of phenomena that may cause errors. This guide applies to any electrically connected ESD controlling electrical power delivered from a source and powering an electrical load. While an independent, certified testing laboratory might be contracted to perform ESD testing, the intent of this standard is to provide guidance to those involved with ESDs wishing to obtain accurate and objective data to aid in evaluating ESD performance.

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.

No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.

No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.

No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.

No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.

No Inactive-Reserved Standards
