Whether caused by an ill-conceived electrical design or other nearby frequencies, electromagnetic havoc can interfere with or cause damage to sensitive equipment. While electromagnetic interference (EMI) and radio frequency interference (RFI) are often used interchangeably, EMI is typically the more comprehensive term. A basic example of EMI is the effect of lightning and its electrical discharge causing static across multiple frequencies. While atmospheric discharges are nearly impossible—if at all—to suppress, there are many methods to suppress EMI in machines that use AC power.
