Voltage Dip definition

Voltage Dip has the meaning given to it in the Grid Code;
Sample 1Sample 2Sample 3
Voltage Dip means a short-duration reduction in Voltage on any or all phases due to a Fault Disturbance or other Significant Incident, resulting in Transmission System Voltages outside the ranges as specified in the Operating Security Standard, and more generally, bus Voltages or terminal Voltages of less than 90% of nominal voltage on any or all phases. Percentage Voltage Dip shall be calculated with respect to nominal voltage.
Sample 1Sample 2
Voltage Dip means a temporary drop (more than ½ cycle, less than a minute) in voltage magnitude below a predefined threshold (typically 90%) of the nominal voltage. When the low voltage extends longer than a minute it falls into the category of Voltage Variation, and events shorter than ½ cycle are classified as Voltage Transients.
