- Open and short circuit tests are performed on a transformer to determine the:
Equivalent circuit of transformer
Voltage regulation of transformer
Efficiency of transformer
The power required for open circuit tests and short circuit tests on a transformer is equal to the power loss occurring in the transformer.
Open Circuit Test on Transformer
The connection diagram for open circuit test on transformer is shown in the figure. A voltmeter, wattmeter, and an ammeter are connected in LV side of the transformer as shown. The voltage at rated frequency is applied to that LV side with the help of a variac of variable ratio auto transformer.
The HV side of the transformer is kept open. Now with the help of variac, applied voltage gets slowly increased until the voltmeter gives reading equal to the rated voltage of the LV side. After reaching rated LV side voltage, we record all the three instruments reading (Voltmeter, Ammeter and Wattmeter readings).circuit of the transformer.
Short Circuit Test on Transformer
The connection diagram for the short circuit test on the transformer A voltmeter, wattmeter, and an ammeter are connected in HV side of the transformer as shown. A low voltage of around 5-10% is applied to that HV side with the help of a variac (i.e. a variable ratio auto transformer). We short-circuit the LV side of the transformer. Now with the help of variac applied voltage is slowly increased until the wattmeter, and an ammeter gives reading equal to the rated current of the HV sideAfter reaching the rated current of the HV side, we record all the three instrument readings (Voltmeter, Ammeter and Watt-meter readings). The ammeter reading gives the primary equivalent of full load current IL.
As the voltage applied for full load current in a short circuit test on the transformer is quite small compared to the rated primary voltage of the transformer, the core losses in the transformer can be taken as negligible here
Thank You for watching
நாளை எனக்கு தேர்வு ஐயா, உங்களது வீடியோ வை பார்த்துத்தான் படித்துக்கொண்டு இருக்கிறேன்.மிகவும் பயனுள்ளதாக உள்ளது.மிக்க நன்றி ஐயா.தாங்கள் மென்மேலும் பல பாடங்களைக் கற்பித்து தர சக மாணவர்களின் சார்பாக நான் வேண்டிக்கொள்கிறேன்.
Sir உங்கள் பணி தொடர வாழ்த்துக்கள். From srilankan electrical engineering student
Share ur friends
Thank U
மிக எளிமையான முறையில் தெளிவாக புரிந்து கொள்ளும் வகையில் எடுத்துச்சொல்லி சிறப்பாக நடத்துகிறார் வாழ்த்துக்கள் ஐயா 🙏🙏🙏❣️❣️❣️
Sir and the team,, my hearty thanks,, for making the video from electronics subjects in tamil,,, my request please do the digital electronics concepts like gates,flip flop, latches etc,, apart from controllers,, because the team already did it,... please
உங்கள் தெளிவான விளக்கம் அருமை
Amazing sir ,IR test (insulation resistance) explain.
at 4:50 time stamp.You've made a mistake,sir..Ammeter has to be connected in series..But you drew Ammeter connected in parallel during short circuit test
No he connected in series only.
Respect sir... your the best ❤❤🎉🎉
Nice explanation sir 🙏
Sir, your explanation is very well. Please explanation to different between vsd &vfd
Sir, very useful your videos, capacitor series connect panna ena aagum, and parallel connect panna ena aagum, itha pathi video podunga sir,
Thanks sir.. good explanation.. God bless
Very tq so much sir
Sir... please explain dry type indoor transformer... Most of the commercial building use this one...
Good explanation thank you sir
Thank you 😊 🙏
So it’s better to connect a load bank for perform the test is in it ?
Suuuuper sir..... thank you very much
Hi sir
How to provide the set the input current in the primary coil??. If we short the secondary coil (I2) , then primary coil will produce the maximum current. In that, how can we limit the primary current (I1)
Hi sir, what is the salary of electrician per day? Or point rate like switch, ac, fan, etc..?
Sir,ennakku konjam puriyala 230 v enpathu single phase itha eppadi 11000 v mathuringa ennakku sollunga sir
great
Super sir thanks
please update on kalvieum as of now
How to calculate the turns in the transformer
Pls explain transformer internal parts
Thankyou so much sir
Super sir...
Thank you sir
Sir turns per voltage transformer sollu inga sir
Sir transformer test method oc and sc ennannu test sir
Sir naan unggakitta DEEE COURSE padikka virumbugiren sir so how to contect you sir
Sir, How can i contact you? Please let me know..
Sir please make videos in Telugu or English
Sir ac motor dc motor function soiluga sir
Sir logic gates pathi soluga sir
Coming soon
Digital Electronics Subjects
Thank U
@@EEEVIDS thank you sir
ஐயா அந்த 10^3 ..
Thank you sir 🙏
