Sidco provides Harmonics Investigations and Survey’s
Measurements for individual and total harmonic distortion (THD) are used to locate specific harmonic emitting sources.
These emitting sources are generated typically from non-linear loads such as electronic devices.
Harmonic Sources
Single-phase
Harmonic 3, 5, 7, 9, 11, 13, 15, 17, etc
- Variable-speed drives
- Electronic phase converters (1-3 phase)
- UPS Equipment
- Switching power supplies
- Electronic ballasts
Three-phase
6-pulse: Harmonic 5, 7, 11, 13, 17, 19, 23, etc
12-pulse: Harmonic 11, 13, 23, 25, etc
- Variable-speed drives
- Oven/heating controls (SCR)
- UPS Equipment
- Battery chargers
Harmonics are categorized as Voltage THDv and Current THDi components and these components can cause various unstable outcomes within the electrical network.
Sidco flexibility provides effective solutions to complex situations.
