In power transformer, a differential relay is a relay that verifies the balance of current between the primary and the secondary face of a transformer. It is also employed in other components of the power system like in protecting cables. Differential relay is also called a unit protection.

Will a transformer Differential Relay act online to line to fault?
, The zone of protection for 2 , 3 or multi windings transformers differntial relay is decided by the location of CT.s at the respective sides i.e. HV. IV OR LV SIDES . Ideally on any fault within zones of these C.T.s the differential relay should act. However sometimes inadequecy of C.T. s ratings like low burden rating, less knee point voltage or improper biased settings may cause the differential relay to operate even on line faults.

Is a relay considered a load?
The relay's coil(s) would be a load, but the main function of a relay is to act as a switch to control power to a larger load.
What is a function of a Buchholz relay?
A Buchholz relay is designed to detect a failing oil-filled power transformer. It will automatically disconnect the transformer and produce an alarm signal.

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 the basic definition of differential equation?
An equation where some terms are derivatives of functions. Usually the problem is to find the function that makes the equation true.
What are the Differentiate the sine wave and cosine wave?
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.

What is the difference between differential and derivative in the field of calculus?
The derivative refers to the rate at which a function changes with respect to another measure. The differential refers to the actual change in a function across a parameter. The differential of a function is equal to its derivative multiplied by the differential of the independent variable . The derivative of a function is the the LIMIT of the ratio of the increment of a function to the increment of the independent variable as the latter tends to zero.

What is the difference between diffrencial relay and a distance relay?
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.
