It is a relay that has two states. in one state a set of contacts will make or break. In the other state the other set of contacts will make or break. One coil operating two sets of common, normally open, normally closed. each set of contacts will change states when the coil is momentarily energized.
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
I think aux relay is part of relay
Earth fault relay and an over current relay Methods to energies an earth fault relay with simulation diagram?
generator lockout relay is a relay that the output of other relays energize this relay and its out put use for tripping of generator. this relay must be reset manually
Interposing relay panel is an Instrument / Electrical cabinet used for hardwired signal (digital inputs and outputs) interfaces between Instrumentation and Control Equipments system and associated circuit breakers,or other electrical devices for monitoring, controlling
In general, a DCS or PLC, handles numerous discrete I/Os. One common I/O module (board) is used to supply 8, 16 or more points. Discrete output circuits from a DCS typically use low power level signals (transistors, micro relays) which cannot be sent directly to the field devices such as electromagnetic valves or motor control circuits. That is why interposing relays are often necessary. These relays play an important role by amplifying the current capacity of the contact signal of the I/O module allowing larger current flow. In addition, discrete input circuits normally can handle only dry contacts or wet contacts of low voltage, which also require interposing relays. For example, let's say the relay of a PLC can only accommodate 0.5A at 220 VAC, but the solenoid which is to be connected to the relay requires 1.2A at 220 VAC. In this case, an interposing relay with contacts rated for operation at 1.2A at 220 VAC would be used as an interposing relay "between" the PLC relay and the solenoid. The coil of the interposing relay should require less voltage and current than the driving relay is rated for, and the contacts of the interposing relay must be rated to handle the requirements of the load (solenoid, light, contactor, motor, etc.).
Protect (from heat) by interposing material. Example: this tire is insulated!

Interposition constitutes the act of interposing that actions that take into account central interests of two sides.
Look at the examples in highlighted text in the passage. Which example shows the Socratic teaching method Plato recorded?
An auxiliary relay is a back-up relay in case the primary relay fails.
The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
It depends what relay you mean - a normal relay has four swimmers (e.g. an IM relay or a freestyle relay) bu relays such as a cannon relay can have more

Swap relay with another like relay.
Do your own homework. ^^^^^^^^^^ I'm pretty sure that if this user wanted a smart remark like yours he wouldn't have posted the question, this website's name is "answers.com" not "smart remarks made by people who have no lives and suck at life.com" thank you.
