Problem with harmonics? Danfoss has the solution
It is important to understand harmonics in order to select the proper solution to mitigate. Harmonics can have detrimental effects on system performance including:
- Distorted current flows through transmission devices.
- Extra heating of power transformers and cables that supply current to the nonlinear load.
- Decreased capacity in local generators
- Nuisance tripping of protection relays and circuit breakers.
- Increased utility costs
- Voltage distortion
View the presentation below to understand harmonics, then choose between several Danfoss solutions which can optimize your system performance to meet the guidelines set forth in IEEE 519-2014.

The VLT® LHD is the first solution to combine an active filter and a drive in one package. It continuously regulates harmonic suppression according to the load and grid conditions without affecting the connected motor. The total harmonic current distortion is reduced to less then 3% on grids with balanced mains, a minimum pre-distortion to less than 5% on grids with high harmonic distortion and 2% phase unbalance. The VLT® Low Harmonic Drive meets all present harmonic standards and recommendations.

VLT® dV/dt Filter MCC 102 are differential-mode low-pass filters which reduce motor terminal phase-to-phase peak voltages spikes and reduce the rise time to a level that lowers the stress on the insulation of motor windings. Reduce the dV/dt values on the motor terminal phase-to-phase voltage – an issue that is important for short motor cables.
