Referring to the figure the type of load is

A line - commutated inverter changes $$dc$$ voltage to $$ac$$ voltage

Thysistor circuits that directly convert poly phase $$ac$$ voltage from one frequency to another frequency are called _______.

Consider a three-phase, $$50$$ $$Hz$$, $$11$$ $$kV$$ distribution system. Each of the conductors is suspended by an insulator string having two identical porcelain insulators. The self capacitance of the insulator is $$5$$ times shunt capacitance. The voltage drop across botton most disc is:
