    Hello Abdullahi Amoo,
    I do not believe that a EV load will pose a serious harmonic problem to the utility system as long as the EV system has been installed properly and the EV unit is a quality product that has been manufactured by a reputable company. Each electrical utility system produces various levels of harmonics due to the nature of our current conventional electrical power generation and distribution systems. Levels of EMF may be reduced by using earth grounding techniques, shielding methods and power conditioning devices. Power quality and harmonics may be detected and monitored using EMF meters.

    Can EV load pose serious harmonic problem to Utility System? If yes, how can such problem be predicted?
