DC equipment monitoring system of substation based on GPRS technology

The feasibility of the composite insulation applied to HVDC equipment;

The long term live examination field for UHVDC equipments, an important part of National Engineering Laboratory for UHV Engineering Technology (Kunming), can be employed to verify the design reliability and practical performance of UHVDC equipments operating at the high altitude so to offer technological support of UHVDC equipment selecting and independently innovating.

This paper discussed the necessity of DC power supply equipment on-line monitoring from importance of DC power supply equipment,the problem of operational maintenance and requirement of field,and bring forward a solution of DC power supply equipment on-line monitoring,This solution is useful for new construction and reconstruction of DC system.
