What is a electromechanically relay?
A relay is an electronic switching device that opens or closes a circuit. An electromechanical relay would be one that is opereated remotely using an electrical circuit that mechanically operated the relay, which in turn opens/closes the second ciruit.
Who developed the first relay operated computer?
Howard Aiken developed the first relay operated computer that is Howard Mark II.

How can we make the distance relay to operate in 3 zones?
as distance relay is an impedance relay & measures impedance interms of current & voltage. first zone : 85% of the selected ist portion's impedance interms of resistance & reactance. normally we use 85% to 90% of ist portion to avoid any human & other CT & PT's instruments errors. secound zone: selected zone ist + 50% of the secound selected portions. Third ZOne: selected zone ist + zone 2nd + 20% of the thrid selected portions. Distance relay is CT & PT operated relay & give us exact location of the fault after measuring the level of the fault current & voltage.
Why to use Vcc in electronic ct?
collector voltage wit respect to ground
Is the Mercedes 230E 1985 speedo operated by cable or electronic?
The speedometer on the 1985 Mercedes 230E is operated by cable. The 230E was in production from 1979 to 1985.
Dear all what direct consequences can be from Current transformer on generator with respect to differential protection relay?
CT's are used as inputs to the differential. If the CT is bad, or it is not wired to the differential correctly, it will cause differential current to be seen by the relay, resulting in a trip.
What is eatx relay?
Eatx stands for electronic automatic transmission controller the eatx relay provides power for the controller and the backup eatx relay is for the backup lights.
What is an egi relay?
An EGI relay is the electronic gas injection relay in the fuel pump of an automobile. This device must function in order for a car to run properly.
Non-directional over current relay?
