OFFSET IMPEDANCE RELAY
Offset impedance relay is also known under names ADMITTANCE RELAY or MHO RELAY
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.
A Buchholz relay is designed to detect a failing oil-filled power transformer. It will automatically disconnect the transformer and produce an alarm signal.
Plogrammable logic array is the set of instructions which makes and breaks the circuit.
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.
A relay will have a control circuit and a function circuitcould be the same feed line. One set of terminals (Hot and Load) can be activated at all times, but will not function until the control circuit is closed. The control circuit has a Hot and a Ground--when activated either by supply hot or ground by switch. The internal coil closes allowing the function circuit to operate. The purpose of this relay is to reduce the spike to the alternator. It takes less current (voltage) to close the coil on the relay than it would to operate the accessory that it controls

mho rerlay is used in long transmission lines
as it is most affected by arc resistance....
MHO distance relays are used to protect andÊdetect faults and the location of faults on a transmission line. It detects faults by measuring and comparing phase angles through a phase comparator.

MHO is a formerly used unit which was used to measure electrical conductance.

Basically, a "relay" is a switch. When you push the horn button you're triggering the relay which in turn feeds power to the horn.
it measure the hardness of material.
There is no such thing as a SMT relay. An SMTP relay, on the other hand, stands for Simple Mail Transfer Protocol. The function of a SMTP is to transfer email messages across two servers of Internet Protocol networks.
