What else can I help you with?
It will not. This relay is a Normally Open relay construction. The contacts are closed only when power is applied to the relay coil. You must use either an SPST-NC (Single Pole Single Throw – Nor?
It will not. This relay is a Normally Open relay construction. The contacts are closed only when power is applied to the relay coil. You must use either an SPST-NC (Single Pole Single Throw – Normally Closed) construction or an SPDT (Single Pole Double Throw) type of construction so a contact closure is presented when there is no power applied to the relay coil.
What the three types of over current protection relay and describe the principles of operation?
over current protection relay
What are the applications of a shaded pole motor?
When the coil in the relay needs to run off an AC signal rather than DC. The shaded pole keeps the relay from "chattering" every time the AC current crosses 0v on the sine wave.
What is the purpose of a coil clearing contacts?
Coil clearing contacts are used in electrical relay systems to ensure that the relay coil is de-energized and to facilitate the proper operation of the relay. When the relay coil is energized, these contacts help clear any residual current or voltage from the coil, preventing unintended activation or malfunction. This is crucial for the reliable operation of the relay, especially in applications requiring precise control and safety. Ultimately, coil clearing contacts enhance the overall performance and longevity of relay systems.
What is ment by restraining coil?
straining coils are winding that we uses to prevent the fault operation of relay
What is Pole discrepancy protection?
Pole discrepancy protection is a relay protection scheme used in power systems to detect discrepancies in the operating characteristics of protection relays during a fault condition. It helps to identify instances where different protection relays connected to the same power system asset (such as a transformer or line) are not tripping in coordination, which can cause delays or maloperation in fault clearing. The protection scheme typically involves measuring the time delay and coordination of the relays to ensure proper operation.

How would you use discrepancy in a sentence?
The couple had a discrepancy with their repair bill.
What is an Induction Relay with shaded pole?
It is a device used to protect Electric Network and loads
What effect would an open relay coil have on the operation of the relay?
An open relay coil would prevent the relay from energizing, meaning the switch mechanism would not close or open as intended. This would disrupt the circuit it controls, leading to a failure in the operation of any connected devices. Essentially, the relay would remain in its default state, failing to perform its intended function.
What would a 1 Form C relay and a 1 Form A and 1 Form B relay be?
Hi All answered in http://zone.ni.com/devzone/cda/tut/p/id/4782 = Relay Forms = 121 ratings | 4.61 out of 5 | Print DocumentRelays are classified by their number of poles and number of throws. The pole of a relay is the terminal common to every path. Each position that the pole can connect to is called a throw. A relay can be made of n poles and m throws. For example, a single-pole single-throw relay (SPST) has one pole and one throw, as illustrated in the following figure. A single-pole double-throw (SPDT) relay has one pole and two throws, as illustrated in the following figure: A double-pole double-throw (DPDT) relay has two poles, each with two simultaneously controlled throws, as illustrated in the following figure: Relays are then classified into forms. Relay forms are categorized by the number of poles and throws as well as the default position of the relay. Three common relay forms are: A, B, and C. Form A Form A relays are SPST with a default state of normally open. Form B Form B relays are SPST with a default state of normally closed. Form C Form C relays are SPDT and break the connection with one throw before making contact with the other (break-before-make).
Can you put the word discrepancy in a sentence?
The discrepancy between you and me is our sex. In other words discrepancy means difference.
What does a double pole refer to?
.............................../ Pole 1 ---------------O O---------------------- | | ................................/ Pole 2 ----------------O O--------------------- | Two single throw switches mechanically joined together so that their individual poles are switched simultaneously. One throw actuates both poles. Example: that doubled air conditioner circuitbreaker. Add another position for each flapper "/ " and you have a double pole double throw. Periods .... were used to place flappers, which should connect to the O's below them. Graphical interface would be helpful. Throw = switching actions available to different circuit paths Pole = a power line connection to switch to the different paths.
What is The discrepancy between the orientation of a compass and true north known as?
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
What is the purpose of a relay call?
A relay call is technology that is used for people who are deaf, hard of hearing, speech impaired, or deafblind. Calls go to a center who then relay them thru keyboard operation.
Where is the starter relay on a Ford Excursion and how do I test it?
Not sure of the location.. not particularly familiar with that vehicle. You should always be getting power at the 30 pole with the test light. With the key in the start position, you should see power at the 86 pole. Take a jumper wire and jump power from the 30 pole to the 87 pole. If the starter engages but didn't with the relay installed, there's your problem. If it doesn't, run the test light ground to the 87 pole and the probe to the 30 pole... if you don't get a light at that point, your problem is in the 87 circuit to the starter.
