Harmonic Analysis
Today LEDs are most popular lighting device. It is energy efficient and environment friendly. But it has a disadvantage of harmonics generation due to function of switching devices in led drivers.
Various research papers are produced to reduce the harmonics generated by led drivers. You can find the more references at our knowledge bank.
Switching devices used in LED Drivers/ SMPS distorts the current wave form. So various harmonics filter is designed to reduce the harmonics.
Accepted Standards
The accepted level of harmonics is defined in:
- IEC 100-3-2
- IS 14700 (Part 3 Sec 2)
Harmonics Limits for Lighting Devices
The limits for harmonics for lighting devices as per standard is given below:
Equipment for Harmonics Analysis
For harmonics analysis of LED Driver user can use SPEA-1 which is manufactured by Embuilt Technologies.
SPEA-1 Capabilities:
- Voltage and Current Harmonics up to 55th Level
- Voltage THD and Current THD Measurement
- Real-time Harmonics Spectrum Analysis
- Data Logging and Reporting Features
- Compliance Testing with IEC and IS Standards
