The most complete tool to support the calculation of high voltage electrical installations.

Free sections:
- Determination of the characteristics of the equipment: rated voltage (Ur), withstand at industrial frequency (Ud), withstand type of lightning (Up), short-term current (Ik)
- Sizing of low and medium voltage insulated cables (≤ 30 kV)
- Calculation criteria for admissible current, voltage drop, short circuit and protection, consideration of different factors for reducing the admissible current: temperature, thermal resistivity of the ground, grouping, sun exposure, etc.
- Multiple installation methods: tray, buried, under pipe, in the air ...
- Visualization of protection relay trip curve and MV cable admissible current
- Protection with transformer limiting fuses
- Earth fault current calculation (isolated neutral and earth)
- PE conductor
- Transformer performance and voltage drop
- Primary/secondary conversions in voltage and current transformers
- Secondary of a transformer acoording to switch position
- Calculation of the transformation center ventilation needs
- Five safety rules
- Consult ANSI codes electrical protections
- Tray sizing
- Representation of 1 IEC curve
- Parameter configuration
Voltages, frequency, conductivity of the conductor material, temperature
MV specific: list type, cable bundle (flat / staggered)
Regulation of LV protections
- Possibility of sharing results

Purchases In-App:
