Relay are operated by small current /voltage connected to Secondary side of Current Transformer and /or Voltage Transformer. The signal stimulates the magnetic substance nearby with the attracting force. This closes or opens the circuit being used in protection purpose.
A device with an overload protection used to control a motor is an Overload Relay.
LBB is local breaker protection
Buchholz Relay is a special type of relay and its only used in transformers, and the main use of this relay is transmission and distribution systemAnswerA Buchholz relay is used between a transformer and its expansion tank. So they are only used (1) where there is an expansion tank and, (2) in substations, where the associated protection relays can be installed.
Lock out Relay is the Master Trip relay( It is a latch relay once operated we have to reset it by manual) Which is used for Generator protection,Transformer protection,Turbine protection (Fixed in indoor Panel, Standard manufacturer only making those relays) if it operated because of any fault in above the after clearing all the fault we have to reset it by hand(normally available 110Volts or 220Volts DC).
What is the purpose of the Merit Systems Protection Board
differential protection relay
reactance relay is used for distance protection of the transmission line....
A device with an overload protection used to control a motor is an Overload Relay.
The purpose of piping as used in plumbing applications is to relay fluids such as water to households.
No there not same
due to the extension of loads they are using the relays for protection.........
over current protection relay
LBB is local breaker protection

It is the one type of coil in the electrical motor starters. It is used to release the switch, i.e. turns off the motor, when heavy load is connected to the motor. It is used for the protection purpose.
The Purpose of a Relay is to control multiple electrical components at once.
The purpose of relay for life is to raise money for cancer and find a cure for it.
