High Current / High Voltage Laboratory

The fo­cus of the ap­p­li­ca­ti­on-driven re­se­arch in the la­bo­ra­to­ry is put on the in­crea­se of re­lia­bi­li­ty and life­time of electri­cal com­po­n­ents ta­king in par­ti­cu­lar into ac­count the as­pects of en­vi­ron­men­tal pro­tec­tion and en­er­gy ef­fi­ci­en­cy. The fol­lo­wing to­pics are cur­rent­ly under investigation on in the la­bo­ra­to­ries for high cur­rent and high vol­ta­ge en­gi­nee­ring (at the joint pro­fes­sor­ship at the Uni­ver­si­ty of Ros­tock):

• electric con­tacts and con­junc­tions (long-term sta­bi­li­ty, aging, ther­mal di­men­sio­ning, de­sign)
• par­ti­al di­sch­ar­ge dia­gnostics and ana­ly­sis of electri­cal com­po­n­ents
• aging of iso­la­ti­on ma­te­ri­als un­der ex­tre­me con­di­ti­ons
• electric arc plas­mas: ex­pe­ri­ments, mo­del­ling and dia­gnostics of swit­ching arcs (see al­so Arc Research La­bo­ra­to­ry of INP)

Available equipment:

• High vol­ta­ge la­bo­ra­to­ry with di­gi­tal mea­su­ring sys­tem in­clu­ding par­ti­al di­sch­ar­ge mea­su­re­ment (ba­sic noi­se le­vel <1 pC), for AC vol­ta­ge up to 100 kV, DC vol­ta­ge up to 130 kV, im­pul­se vol­ta­ge 135 kV
• Par­ti­al di­sch­ar­ge dia­gnostics (IEC 60270, UHF), impedance mea­su­re­ment sys­tem (35 TΩ, pro­be vol­ta­ge 10 kV), dielectric re­s­pon­se ana­ly­zer (200V, 100 μHz ..5 kHz)
• Cli­ma­te la­bo­ra­to­ry with cli­ma­te cham­bers for coo­ling and warm up cy­cles (-70 - +180 °C), ther­mo-cham­bers (+250 °C)
