HVDC

HVDC stands for high voltage direct current in the electric power transmission system. The high voltage direct current system uses direct current (DC) for the transmission of electrical power through transmission lines in contrast with the alternating current that is the AC system. The HVDC is used to transmit bulk power point-to-point through long distances transmission lines. Power is rapidly transferred because the efficiency of transmission lines is greatly increased over long distances due to HVDC lines.

Question

A string of Suspension Insulators consists
of 10 units. If the Voltage across the string
is 50 KV and the Voltage across the unit
nearest the line is determined to be 16 KV,
calculate the String Efficiency of the
Insulators. Type your Final Answer (with
correct SI UNIT) in the box provided.
