A relay is basically a controllable switch that connects a supply voltage to a load. If the relay is switch such that the load is not connected, that could be considered an open load. If it is switched the other way the load will be connected to its supply voltage. A defect in a relay would be something that caused it not to function correctly. It could be in the switch portion of the supply portion of the relay. Hence you are referring to different things and a defect may or may not cause the load to be open.

Is feeder protection relay and ring main unit protection relay same?
No there not same
What is the defect notification period?
It is same as DLP ie Defect liability period, which is generally 12 months from the completion period of any project.
Does defect mean the same thing as defective?
No, to defect is to move your allegiance to the opposite side in a struggle or war. Defective means something does not work as it should.
Is a relay and a diode the same?
No.
Is a current relay same as potential relay?
current relay are using for over current low state & high state.but potential relay are related to voltage.
Normal open relay?
A relay is an electrical device that acts like a light switch. But instead of a person turning the switch off and on, it is done by energizing it from a remote source. So when you hook two wires to a relay, if the relay is normally open, there will be no connection between the two wires until the relay receives a signal (outside source to energize relay) to close. Simply put, an open relay is the same as a light switch that is turned off, and will always be off until told to turn on.
How relay operate?
Same as every other relay. All relays have a control side and a load side. The control side has 1 power and 1 ground. It also has a coil of wire that becomes electromagnticly energized causing the LOAD side to close and allow current to flow. So you hop in, turn your ignition key and then the request is sent to the ECM (cars computer) to see if the conditions are correct for the car to be started. The control side of the relay is then energized by the ECM providing a ground for the relay. Current will then be allowed to flow as the control side causes the load side engage.
What is fault masking?
An occurrence in which one defect prevents the detection of another. [After IEEE 610]. It is same as Defect Masking.
How starter relay operates?
Same as every other relay. All relays have a control side and a load side. The control side has 1 power and 1 ground. It also has a coil of wire that becomes electromagnticly energized causing the LOAD side to close and allow current to flow. So you hop in, turn your ignition key and then the request is sent to the ECM (cars computer) to see if the conditions are correct for the car to be started. The control side of the relay is then energized by the ECM providing a ground for the relay. Current will then be allowed to flow as the control side causes the load side engage.
What is AC rating DC rating wrt Relay contact or contact of contactor?
The contact rating is normally given in AMPs or HP and refers to the load the "switch" in the relay can handle. The manufacture will specify the relay contact rating in the data sheet. This rating depends on the current being controlled by the relay, the connection type (how the relay is mounted) and the duty. A Normally open relay in pilot duty (clicked closed all day) may be only 10% of the same relay in intermitted contact duty. DC current requires a higher contact rating then AC. For example a relay rated at 1A @ 24vdc should also handle 1A @ 120vac and as the voltage increases the contact rating will lessen.
What is defect cascading?
Defect cascading explains how one defect leads to other defects. For Example, employee application salary calculations are not correct when totaling Basic, Tax and Gross, so for this issue defect raised. In this case other modules will block and also same defect will exists in all those modules due to this defect. This is called Defect Cascading.
Is feeder protection relay and ring main unit protection relay same?
No there not same
Is 89 Camaro fuel pump relay wired same as 89 pickup fuel pump relay?
They are probably the same relay. Compare the relay part numbers.
Are turn signal relay and flasher the same thing?
The turn signal relay and the flasher relay are the exact same thing. The relay switch controls the turn signals.
What are dobereiner's triads defect?
the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
What is the defect notification period?
It is same as DLP ie Defect liability period, which is generally 12 months from the completion period of any project.
Does defect mean the same thing as defective?
No, to defect is to move your allegiance to the opposite side in a struggle or war. Defective means something does not work as it should.
