| Abstract |
Recently, application area of the thyristor is extends to power conversion systems, such as HVDC, BTB, SVC and FACTS. Therefore, reliability diagnostic technique on thyristor is needed to obtain stability and maintenance of power conversion systems. To measure the characteristics of the thyristor, test equipments which based on IEC 747-6 and KS C 7023 standard are needed. In this paper, we presents the design and manufacture of the test equipments for 6.5kV/4.2kA thyristor which used in thyristor valve of HVDC conversion systems by using test standard. Voltage, current, dv/dt and turn-off time test equipments were designed and manufactured. Each systems were made separately, but unity operation can possible. |
