Zusammenfassung:46,446 SYMMETRICAL COMPONENT SEQUENCE FILTER A symmetrical component sequence filter which provides a signal responsive to a predetermined sequence quantity of an electrical power system, while using only one phase shift other than 180 degrees. A single reactive element provides the phase shift. A single adjustable resistor calibrates the filter when the reactive element is non-precision. Selecting a precision reactive element eliminates even the single adjustment. The symmetrical component sequence filter enables both a positive and a negative sequence component to be simultaneously derived from common processing circuitry, requiring only one additional reactive element.
