relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.
Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.
The traditional form of a relay uses an electromagnet to close or open the contacts, but other operating principles have been invented, such as in solid-state relays which use semiconductor properties for control without relying on moving parts. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called protective relays.
Latching relays require only a single pulse of control power to operate the switch persistently. Another pulse applied to a second set of control terminals, or a pulse with opposite polarity, resets the switch, while repeated pulses of the same kind have no effects. Magnetic latching relays are useful in applications when interrupted power should not affect the circuits that the relay is controlling

सर आपका विडियो बहुत अच्छा लगता हैं थैंक्यू सर,👌👌👌👌
nice helpfull video sir
Nice information thank you sir
Very knowledgeable video
Good explained
Sir ji NYC video he aapka
Nice video
Mai bhi agra me sub station operator hu
Good 👍
Super sir
Current setting kaise badhate hai... Uska video banao
Good sir
Fault distance calculation video banaye
Railway Electrification Ahmedabad Project
Plz provide OHE fault distance calculation formula.
Agar asida ka panel hai to Z value use 4.068, se guda kar denge uske bad Jo aaega vah distance hoga Km
Z×4.068=K.m
Sir window alarm Ki sampurn video banao
Ohe fault distance formula please?
Tss me Jo current note down ki jati hai wo feeder cb ki current hoti hai ya LV ki current
Please reply
TSS me current HV aur LV dono side Ka measure hota h...
Did you get your answer?
Yes, I got it.
Ok
Ery nice topic, but is there any English translation?
What is the language? Nice English text.
Hindi language
Sir tss me join honekeleya intermediate chalega sir
ITI 10th pass
Sir apne RX value nikale jaroor, but apne batya nahi ki ye kon sa button ko click karne se aaya, not stisfying me
Capacitor CB ki panel ki drawing mil sakti hai kya
Ashida panel
Fault distance formula kya
Aastha panel relay ke bare mein Janna hai
Aastha panel ke bare mein Janna hai
kaha ka tss hai ye
Gujrat ka hai ye tss
BM operate Karo sir manually
Next video me karunga
Bm ka full form batana bhai kya hota hai to
@@Way4study pls tell me bm full form
Fault calculator pe video bana dijiye
Bm ka full form batao
Breaker mechanism
Breaker mein switch
Breaker off main line switch
sir ye substation kha ka he
Gujrat
sir diploma in electrical engineering huva he to substation ke job keliye apply kase kare
Online apply karo
Naukri.com par
LinkedIn pqr profile banao aap
Aur usme poora mention karo details....
Please send me
Single or double line
