Nonlinear loads, such as Variable Frequency Drives and UPS systems, reduce energy costs and provide system efficiencies. However, they also can create harmonic distortion.
High Frequency Noise Applications
Unwanted high frequency electrical noise can cause equipment to malfunction. EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference) are two types of electrical noise.
Motor Protection Applications
Motors can be damaged by voltage overshoots and common mode currents.
