A voltage dip is a short, temporary drop in the voltage magnitude in the distribution or customer's electrical system It may be caused by various faults in the transmission and distribution networks, faults in the connected equipment or high inrush and switching currents in the customer's installationWhat causes a power dip?

## Voltage Drop Adams Electric

voltage at electrical equipment will be less than the output voltage of the power supply This will result in inductive loads (ie motors, ballasts, etc) operating at voltages below its rating which in turn can cause them to overheat — resulting in shorter equipment operating life and increased cost, as well as inconvenience for the consumer Undervoltage for sensitive electronic· X/R Ratio Calculation X/R ratio is the ratio of inductance to resistance of the power grid up to the point of fault Near to large generating stations and large substations, this ratio will be high At the tail end of long distribution lines and for low voltage systems the ratio will be lower If the X/R ratio is 10, it means the inductance ofSOURCE IMPEDANCE CALCULATION IN POWER SYSTEMS – Voltage
