IEEE 519 Harmonic Distortion Testing for Power Supplies
The IEEE Standard 519-2014 provides guidelines and requirements to limit the contribution of harmonic currents injected into utility power systems by nonlinear loads. This standard is particularly important in ensuring that equipment like power supplies and chargers do not cause adverse effects on the quality of electrical power distribution networks.
Harmonic distortion testing for power supplies aims to ensure compliance with IEEE Standard 519-2014, which specifies limits for harmonic current distortion caused by nonlinear loads. Nonlinear loads such as power supplies and chargers introduce harmonic currents into the power system, leading to higher-order voltage distortions that can affect the performance of other equipment connected to the same network.
Our testing service ensures that your power supply or charger meets these stringent standards. During this process, we use advanced instrumentation to capture detailed waveform data on the input and output voltages and currents. This helps identify any harmonic distortion present in the signal and assesses whether it falls within acceptable limits as defined by IEEE Standard 519-2014.
The testing procedure involves several steps:
- Installation of specialized equipment capable of capturing waveform data at various points on the power supply or charger.
- Data collection over a specified period to ensure comprehensive coverage of potential harmonic distortions.
- Analysis using specialized software to determine compliance with IEEE 519 standards.
- Reporting and certification upon successful completion.
The importance of this testing cannot be overstated, especially for manufacturers aiming to meet regulatory requirements or improve the reliability and efficiency of their products. By ensuring compliance with IEEE 519-2014, companies can enhance product performance while reducing potential risks associated with non-compliant devices.
| Parameter | Description | Units |
|---|---|---|
| Harmful Current Distortion | The percentage of harmonic content in the current waveform. | % |
| THD (Total Harmonic Distortion) | The ratio of total rms value of all harmonic currents to the fundamental frequency current. | % |
Scope and Methodology
The scope of our IEEE 519 Harmonic Distortion Testing for Power Supplies includes a comprehensive examination of both the input and output characteristics of power supplies and chargers. This ensures that any harmonic distortions generated by these devices are identified and addressed.
Our methodology involves:
