Project assignment:
Activation of groundwater extraction pumps
 
Implemented solution: 
 
Uninterruptible power supplies (UPSs) with batteries, sensors and a signal lamp have been supplied for the groundwater extraction system. 
 
   The rack mounted UPS - with  batteries 24V, which convert 24V to 220V.
 
Water level sensors are installed in a well where groundwater is collected. There are 2 pumps installed in the well, one main and a spare pump. The sensors give a signal for pump start and stop.
 
When the water level in the well does not exceed the critical point then pump 1 operates, otherwise the backup / alarm pump is activated.
 
Above the door is a signal lamp with an alarm that is activated when the backup pump is in operation.
