They're completely different, used for different applications (usually). A distance relay uses both current and voltage. A differential relay uses only current. A differential relay usually has harmonic restraint capability, while distance relays ideally track system frequency. Differential relays require fast operation, while distance relays may not be required to operate as quickly. Distance relays have more issues with operating for out of zone problems than differential relays. There are many more, but this gives an idea.

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 is the use of reactance relay?
reactance relay is used for distance protection of the transmission line....
Why impedance relay is called as distance relay?
because the distance is propotional to the impedance of the line ,so the operation of the impedance relay comes into picture when the impedance seen by the relay is less than the pre-setting value.When a fault occurs ,the current increases to a high value and so the Impedence decreases and the relay actuates
How does a distance protective relay work?
The distance relay trips when a fault occurs at a distant or a remote place in the electric transmission line. There is a mechanism based on the impedance calculation of the distance of the transmission line after which it is accurately known where the fault has taken place. Thus the distance protective relay can trip the circuit & prevent the fault to be carried further and also can indicate the location of the fault.
What is the difference between solid state relay and safety 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 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
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 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.
Which relay is used for long transmission line?
distance relay..........
Difference between overload relay and over current relay?

What is the difference between a relay and a dash?
Well, darling, a relay is a race where team members take turns running a specified distance, passing a baton to the next runner. A dash, on the other hand, is a short sprint race usually run individually over a specified distance. So, in simple terms, relays are all about teamwork and batons, while dashes are all about individual speed and glory.
