Difference between overload relay and over current relay?
due to the extension of loads they are using the relays for protection.........
What is the difference between circular relay and shuttle relay?
the difference is that in a shuttle relay, you run back and for(e.g. you run 100m to the next person and they run back to where you started, where the next person is waiting e.t.c.). A circular relay is around a track e.g. a 400m track you each run 100m going round the track. hope this has helped.
What What is the difference between buzzer and speaker?
BUZZER IS SIMPLY A RELAY THAT MECHANICALLY OPENS AND CLOSES. A speaker is a coil suspended into a magnetic flux responding to AC signals
How negative sequence current calculated in numerical relay?
In numerical relays, negative sequence current is calculated using the measured phase currents and voltages. The relay computes the negative sequence components by applying symmetrical components analysis, which decomposes the three-phase currents into positive, negative, and zero sequence components. This is typically done using the formulae: (I_{2} = \frac{1}{3}(I_a + aI_b + a^2I_c)), where (a = e^{j120^\circ}) represents the phase shift. The relay continuously monitors these components to detect unbalanced conditions, which may indicate faults.
What is the difference between rated current In and tripped current?
"Rated current" is the current the device (motor or transformer?) is designed to handle at full load. "Tripping current" is the current where a protective device (fuse, breaker) will open to protect the device from overload/overheating. "Tripped current", may be the current the tripping device measured prior to making the decision to trip, if you are reading this from a digital protective device like a relay or OCR.
What is the difference between solid state relay and safety relay?
not sure
Numerical and microprocessor relay comparison?
Numerical relays are all microprocessor based, but there are relays that take the advantage of microprocessor technology and are not fully numerical. In other words, if a relay is fully based on processing the samples of input signals it is numerical relay.
What is the difference between a relay and an auxiliary relay from constructionapplication poin of view?
I think aux relay is part of relay
Is there a difference between the main relay and the fuel pump relay on the 2000 Honda civic ex?
They are the same relay.
What What is the difference between a humidistat and a dehumidistat?
The difference is the relay operation.Normally opened or normally closed.If you add an external spdt relay,you could have a humidistat/dehumidistat.

What are memory elements in digital electronics?
Relay
What is physical medium for frame relay?
its Digital
What is the difference between an earth fault relay and an over current relay?
earth fault relay is also a type of over current relay but the set value of current or relay sensing current is much less than the maximum load current.in over current relay relay sensing current ise than maximum load current mor
What is the difference between a dash and a relay?
A relay involves 4 people passing on a baton for the race (4X100, 4X400 etc.) A dash is like a sprint and is run individually (100m 200m 400m etc.) The difference is that a relay is run with more than one person.
Is there any difference between the switching action of relays and contactors?
No, there is not any difference between the switching action of a relay and a contactor. Both of these devices are operated by an electro magnetic coil.
What is difference between high impedance busbar protection scheme and low impedance busbar protection scheme?
high impedance circit provides a varistor unit which has stabilising resistor which ll protect the relay from being operating for maloperations like through fault, CT faults whereas this varistor unit is provided internally in an numerical relay where the CT of class 5P can be used.
