At a certain load current value corresponding calibration relays, contact C closes, current flows kekumparan disc (induction) A rotating disc that moves close pal D and E so that the trip coil contact (IC) and the current gets mentrip PMT. The time delay relay is done by setting the distance between the contacts pal D E.<\/p>\n
At a certain value of a relatively large current, appropriate calibration, shut the ignition coil IT and TC direct working download trip PMT (instantaneous relays work). Contact the manual trip trip PMT is used to download manually, not through the relay.<\/p>\n
Intrusion detection tools such as relays. Relay gives orders to the trip coil, the coil when the work will move the opening of the termination of labor (men-trip PMT) voltage freed from the affected plant parts and short circuit fault current that occurs can damage the equipment has been removed.<\/p>\n
Information
\nA = coil Iinduksi;
\nTA = current transformer;
\nB = electromagnet to close contact C
\nC = Contact circuit induction coil cover;
\nD = Pal contact closure located on induction puck, spun with the puck induction;
\nE = the contacts are closed by Pol D
\nTC = Trip Coil dropped PMT
\nIT = Instantaneous Trip<\/p>\n<\/div>\n
