“…The effect of harmonics in the losses of the transformer and its lifetime will be summarized, which is a handful in order to evaluate the protection level given to the distribution transformer by each HDT configuration. Generally speaking, grid voltage harmonics affect the magnetic core losses, while load harmonics affect the winding and structure losses [107].…”

“…The applied voltage magnitude has a critical impact on the insulation materials of the transformer, as high dv/dt can create high electric fields. In the presence of distorted grid voltages, the dv/dt increases, accelerating the degradation of the insulation materials and reducing the transformer lifetime [107]. In [102], different nonlinear voltage profiles have been studied and it is shown that they have a drastic impact on the transformer no-load losses, and increase the maximum flux density of the magnetic core.…”

“…Even though induction motors are not under serious threat from harmonics as synchronous generators, excessive harmonic stress can drive the equipment to overheat [21][22][23][24][25][26][27]. In power systems where capacitors in resonance with the network are enhancing one or few harmonics, this becomes critical with motors.…”

“…However, it is unable to distinguish the dominant harmonic injector at the PCC and billing losses associated with it [2]. Also, harmonics affects the electrical equipment insulation by overheating, causes malfunctioning of protection devices and data loss in communication network due to the interference [3].…”
