Ensuring Reliable Power Quality from Portable Generators for Sensitive Loads
This white paper reviews power quality data from various portable generators, comparing brushless alternator and inverter types. Findings show that inverter generators consistently deliver lower total harmonic distortion (THD), quieter operation, and greater fuel efficiency, making them more suitable for sensitive electronic loads. Proper generator sizing and the use of voltage regulation or UPS systems are critical to avoid damaging connected equipment during outages or transitions.
Key topics include:
- Types of Portable Generators
- Power Quality Analysis
- Load Limits and Sizing Considerations
- Noise and Efficiency Comparisons
- Transition and Protection Strategies
Why utilities should care:
Understanding the differences in generator power quality, noise, and efficiency enables better selection and deployment of backup power solutions, reducing risks to sensitive equipment and ensuring reliable operation during outages or remote deployments.
