My project work was to plan the electricity system of two metal industry halls. First of all I calculated the gross and actual power, the currrent values then the coincidence factor and the utilization factor of consumers. Furthermore I was aware of the power and current values, I calculated the minimal cross section of wires, the voltage drops, the maximum lenght oof wires and the fault current. I planned reactive power compensation for the whole factory. I planned also external and internal lightning protection system for the buildings. I calculated the lighting network with the efficiency method. Then I presented and chose the electrical devices. Then I wrote about the modes of protection against electric shock.

Finally my last exercise was to draw the electrical plans. These are found in the Appendix:

• One-line plan of the TFE distributor

• One-line plan of the FE-2 distributor

• One-line plan of the FE-3 distributor

• One-line plan of the IE-1 distributor

• One-line plan of the IE-2 distributor

• One-line plan of the Control distributor

• One-line plans of the CS distributors

• Plan of the 1st and 2nd Halls’ external lightning protection system

• Plan of the 1st and 2nd Halls’ lighting network
