A power system composes of various electric facilities such as electric power generator, switch gear, circuit breaker, transmission line, distribution line, and electric load. It is distributed through wide spread area and its characteristics changes in real-time basis depending on operating and load condition.

Considering an effect of power system’s fault to the industry and maintenance period, through its prompt restoration and recurrence prevention through an analysis of a cause should be important. Also during a system operation, such solution is needed to prevent any system fault through analysis of electric signal status

Thus in a power system industry, system monitoring, analysis and fault preventions are getting more attention. Through acquiring data about which operational state of each power system facility and protection/ control system, a data analysis and prevention will be implemented.

A fault recording panel is used for analysis of trouble’s cause and operation status of system. When a power system has an abnormal condition (fault, power swing, disturbance, etc), it utilizes by recording and analyzing not only activation status of system’ s protection and control device, but also electric data (voltage, current, frequency, active/reactive power, power factor, etc).

GABO’s fault recording panel has a digital fault recorder (SIMEAS-R) made from SIEMENS, in order to guarantee a reliability. By having accumulated knowledge in manufacturer technology of protection panel, and experienced professionals, we strive to accomplish noise immunity, stable earthing, durability, insulation, assembly, all of which being incorporated in order to generate products of credibility.
