WebThe negative reactance of the capacitors compensates for the longitudinal reactance of the line and reduces the transmission angle. The capacitor bank can be placed e.g. at the mid-point of the power line. The short-circuit current and voltage at the relay depends on the location of the series capacitor in relation to the relay location. WebContributed the production of location case designs, cable core plans, front panel diagrams for main line .
