For operation of HV AC and DC systems a EMC proven control system is required. The control system consists of an operating terminal (OT), a Windows® laptop (HMI) and a control rack, depending on the power of the HV system, with built in power components such as switches, compensation, filters, frequency converter etc.
The control systems can be operated fully manually, semi-automatic or fully automatic. It is possible to use timer functions, as well as predefined individual test sequences.
HV On/Off/Emergency Off
Voltage / Frequency / Inductance Up/Down/Fast/Automatic
Output voltage measurement (RMS/Peak/sqrt(2))
Security functions connected by wire
Flash detection with hold function
Password protected limiter and calibration section
Automatic voltage control
Fiber optic connection to PLC
Data recording and reporting
In order to comply with the high EM stresses occurring during the operation of HV tests systems, the control system is especially developed to ensure a reliable operation throughout years. All data interconnections are realised by optical fibres, while safety relevant functions such as interlock (doors etc.) and emergency off are hard wired. The use of industrial proven components and careful grounding of those, as well as protecting all analog inputs ensures transient proven operation, even under high stresses, such as gas breakdowns.
Sets of spare parts are available in addition to guarantee 100% availability.
