Medium Voltage Calculations

Medium and high voltage electrical installations (cables, protections, etc.)

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
