The IVPower, software for fault analysis and power system monitoring, is designed to complement power system protection and control systems by providing a detailed view of power system disturbances. It uses disturbance recordings and event logs as the main sources of data.
Analogue signals of the disturbance recordings are used to perform automatic fault detection and analysis at power system level. Status changes of process signals in the event logs complement the binary signals of the disturbance recordings and together they allow analysis of the behaviour of protection relays and circuit breakers.
IVPower provides reactance-based fault location using measurements from one, two, or more terminals of power lines or cables. A few minutes after a fault, IVPower can provide time-sensitive and crucial information needed for remedial actions to operators and experts by email or text message.
