Web• Static capacitors or synchronous condensers may be connected to the tertiary winding for reactive power injection into the system. • A delta-connected tertiary reduces the impedance offered to the zero sequence currents thereby allowing a large earth-fault current to flow through the protective device facilitating its proper operation. WebFor example, when testing a CT on the H1 to H3 primary delta winding, you would short the H3 and H2 bushings together. Separate from this, you would also short all secondary terminals (e.g., X1, X2, X3, and X0 if it is a WYE winding). Finally, you would short the tertiary terminals if the transformer has tertiary windings.
