DIGSI 5 offers superior usability and is optimized for your work processes. Only the information you actually need to carry out your tasks is shown.

These can be reduced further using expanded filter mechanisms. The consistent use of sophisticated, uniform mechanisms in the user interfaces requires less training. The IEC system configurator is the manufacturer-neutral solution for the interoperable engineering of IEC products and systems. DIGSI 5 comes in different variants Compact, Standard, and Premium that provide different functionalities: The Single-Line Editor allows you to define a substation and the primary equipment graphically.

Connect those elements to the protection functions of your protection devices. Take your single-line diagram and convert it into a display picture. You can define your own symbols as well. You can configure additional functions like interlocking of the devices graphically with the CFC Editor.

Figure shows the logic diagram of the overvoltage protection element. Figure Logic Diagram of the Overvoltage Protection 6. Under- voltage protection is generally used to load shadding and loss of p … Messages and Measured Values; Recording of Event and Fault Data A series of operating messages provide information about conditions in the power sys- tem and the 7SJ Measurement quantities and values that are calculated can be displayed locally and communicated via the serial interfaces.

Messages of the 7 … This will prevent the user from being able to set the device or perform other actions. To avoid this possible problem, current supervision must be set ON. Before the device is energized for the first time, the device … After the set time has expired, the pickup settings automatically return to their original setting.

Low-current single-phase faults on the low voltage side that result in negative phase-sequence current on the high-voltage side can be detected with the negative-sequence protection. If the control switch is connected to a circuit-breaker bypassing the internal control function, manual detection using a binary input is implemented.

This can compensate for initial inrush when energizing a circuit without compromising the sensitivity of the overcurrent elements during steady state conditions. Asymmetric short-circuits with currents 7s6j00 can be smaller than the largest possible load currents or phase interruptions are reliably detected. Furthermore, low level single-phase and two-phase short-circuits such as faults beyond a transformer as well as phase interruptions can be detected.

Interruptions, short-circuits or crossed connections to the current transformers are detected. The tripping time t is calculated in accordance with the 7aj tripping characteristic complete memory in accordance with IEC In this case, reverse interlocking provides high-speed busbar protection in radial or ring power systems that are opened at one point.

If the internal control function is used local or via serial interfacethe manual closing function is available without any additional wiring.
