Power system harmonics occur when electronic devices draw energy in short pulses, causing distorted voltages and negative effects on system performance. Non-linear loads, such as devices with solid-state switching power supplies, produce harmonic current. Engineers use various methods to reduce harmonics, including efficient designs and isolation and delta-delta transformers. Power system harmonics are the by-products […]

Electronic devices such as computers and variable frequency drives cause power system harmonics, resulting in distorted voltages and negative effects on system performance. Non-linear loads produce harmonic current, causing equipment to operate erratically and power system inefficiencies. Engineers use various methods to reduce harmonics, including efficient designs and isolation transformers. Power system harmonics are the […]
