Evaluation of the Impact of Harmonics on Electric Machine Reliability
Power, magnetic and ground harmonics have a negative impact on the reliability of your electric motors both electrically and mechanically. We often focus just on the power harmonics when reviewing information on power quality, but rarely view the self-generated electric machine harmonics and the harmonic content present in grounds and neutrals. Over the past several…
Electrical and Current Signature Analysis in Standards a 2022 update
On December 1, 2022 I received my usual daily IEEE standards updates for voting which included IEEE P1017.4/D1, “Draft Recommended Practice for Testing and Rating of Electrical Submersible Polyphase Induction Motors.” This would be the complete new draft of such a standard developed by the Petroleum and Chemical Industry Committees of the IEEE Industry Applications…
Impact of Electrical Reliability and Precision Maintenance Programs on Energy and Environment in Commercial and Industrial Facilities
What is the impact of an electrical reliability program? Or even the application of a precision maintenance program Overall, the transition to a planned maintenance program from a reactive program has been identified by the US Department of Energy (US DOE) Industrial Assessment Centers (IAC) as having at least 14% improvement of all energy consumption…
Update Energy Savings through the Application of Neutral Harmonic Filter: A Case Study
It is established that neutral and ground harmonic content will load transformers and systems. Prior work has been limited as to the direct relationship of this additional loading on power consumption for a facility. Over the past 24 months applied research has been performed on the measured impact of neutral and ground harmonics and energy…
EMPATH Continuous Monitoring Special Applications for Energy Analysis
The EMPATH™ family of Electrical Signature and Motor Current Signature Analysis (ESA/MCSA) systems go well beyond analyzing electric motors, generators and wind turbines. It provides prognostic and time to failure estimation (TTFE) capabilities for AC/DC electric motors, synchronous machines, servo motors, machine tools, generators – including utility scale, and transformers. Not only will it identify…
