remote motor star delta starter with dry run and single phasing preventer cct diagram

The Star/Delta starter is generally manufactured from three contactors; and electromechanical timer and a thermal overload for operating a 3 phase motor at 440 volt at ac mains supply 50 Hz. The interlocking arrangement of all the contactor coils is traditionally wired in 440 volt AC.

This project uses a system to start a 3 phase motor at 440 volt AC mains supply 50 Hz with a set of 12 volt DC relays in star mode first and then to delta mode by an electronic ....etc

CLIMATE RESPONSIVE SHELTER FOR WARM-HUMID CLIMATE



NATURE OF THE CLIMATE
Warm humid climate is characterized by high rainfall and high humidity. Most prominent characters of this climate are hot, sticky conditions with continual presence of dampness. The temperature conditions of the atmosphere ranges from 210c to 320c.the temperature difference between the atmospheric zones are very low.as a result, in these climatic zones, winds are very light and sometimes they are non-existent. However, heavy ....etc
