HAZARD AND RISK ASSESSMENT OF HV SWITCHGEAR …· PDF fileModern metal-enclosed HV switchgear has implicitly un-dergone the procedure of risk assessment several times during its development cycles. The risk caused by HV switchgear is in fact low, as verified by long service experi-ence. However, a rising issue is, whether standards for HV switchgear and controlgear really cover hazards comprehen-sively.

HVDC Transmission System Basics, Block Diagram, Working ...· If the power flows in reverse manner (i.e., B to A) then converter-B acts as rectifier and converter-A acts as an inverter. Normally, 12 pulse configuration is used for converter A and B to reduce the ripple voltage. The DC output of the converter is filtered by DC filters and smoothing inductors to eliminate the DC ripples.
