SIEMENS SOFTWARE ANALYSIS FOR CUSTOMER-SPECIFIC APPLICATIONS-LINE CONDITION STUDIES

Siemens optionally offers software analysis (simulation) based on Cigré studies to examine and conduct preliminary tests of customer-specific applications as a way of determining the optimal, cost-effective solution. With this approach, the customer only needs to equip particular phases or individual line segments with line surge arresters, and can still ensure sufficient lightning protection of the overhead line.

In the first phase of an analysis, all important parameters of the transmission line under study are entered into the simulation software, and the installations to be examined are selected. This approach takes the following factors into consideration:

• Line parameters: operating voltage, number of three-phase circuits, ground wire data, length, span length and sag on line, conductor type, diameter, and clearances
• Tower data: tower surge impedances and footing resistance, tower geometry (position and distances of the individual phases and any existing ground wires)
• Insulator data: arcing distance, connection length, rated lightning impulse withstand voltage
• Lightning activity: keraunic level (lightning strokes per year and km²), network topology (elevation profile)
• Customer priorities: fewer short interruptions, prevention of phase and multisystem short-circuits, elimination of ground wires
