POWER QUALITY SYSTEM

DIGITAL FAULT RECORDING

The experience with disturbance recording systems has shown already how valuable this information is in order to allow for a better understanding of the steady-state and dynamic behavior of the system. The complexity of electrical power systems has increased and in the actual interconnected power system influences a wide area monitoring has also become essential. Therefore, disturbance recording and wide area monitoring is about the understanding what is going on with power system considering the wide grid circumstances, where fault location, protection behavior and system stability, through phasors measurement monitoring are analyzed.

With a high sampling rate, this unit records all relevant information for further analysis of short-circuits, breaker opening and closing behavior, reaction of CTs and VTs on network disturbances, etc. With a high recording capability and with real-time synchronization capability, the system can observe and monitor a huge number of feeders and power equipment.
