A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
Lbb means local breaker backup protection
function of static relay
function of capacitive voltage transformer is measure high transmission voltage with low range voltmeter and oprate the relay circuit to oprate CBs.
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.
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.

The Legislative Budget Board, LBB, has many responsibilities. One responsibility is to adopt constitutional spending limits for each fiscal year.

OFFSET IMPEDANCE RELAYOffset impedance relay is also known under names ADMITTANCE RELAY or MHO RELAY
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.
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.
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.
you can take thin wires up to a relay then run thicker wires to lights or do you mean a bulb fail relay.
An EGI relay is the electronic gas injection relay in the fuel pump of an automobile. This device must function in order for a car to run properly.
