Tan delta testing and it's basics including safety instructions

It's the basic guidance for tan delta test.
Tan delta = Ir/Ic
That is the basic equation. Everyone knows this equation.
What I wanted to focus on is the basic concept of insulators to which acts as a capacitor.
Basic equations-
- tan δ or D.F = IR/IC
- P.F = IR/(IR+IC)
Acceptable value of tan δ ≤ 0.007 or 0.7% AT 20̊ C
tan δ test can be carried out on following equipments-
- Cable
- Transformer oil, winding, bushings
- CVT
- Current transformer
- Any insulator
Safety points to remember-
- Always ensure proper earthing of the equipment before testing.
- Do not keep the tan δ point open after testing. The open tan δ point may cause rise of potential at the point which will result into flashover & equipment damage further.
- Keep the C.T/CVT secondarys shorted & earthed properly during tan δ testing.

Best explanation I found on UA-cam. thankyou sir for sharing your valuable knowledge with us I request you to please make a video on stability test.

[@ashishvitekar3474]

Very nice explain and very informative video's keep it up.
Thank you very much

[@satya7077]

Nice explanation sir... I want more video on numerical relay setting calculation, testing and coordination.

[@electricalchakra798]

Thanks

[@harshalpatel214]

Best ever explained on you tube ....sir....I want more videos regarding Transformers all testing with details....like magnetic balance, winding resistance, seperate source, induce over voltage, no load, load loss, Impulse, PD etc (all test regarding Transformers).....plz plz....

[@rahilahmed5899]

Very nice explanation. one of best I found on this platform. I really respect your effort 👌

[@Naveenkumar-qb9xb]

Excellent Explanation Brother. Thank You

[@souravhalder6691]

Nice video... can you make a video on HAZARD RISK CALCULATION (HRC) based on Arc fault energy of different type of electrical system like heavy , medium & small size industries

[@8017345933]

Sourav da onek din por dekhlam. Darun presentation. Helpful. Looking forward to see more from you. Subscribe korlam.

[@appliedelearning8651]

Last uploaded video three months ago. Didn't upload any more videos after that.Please Upload more Video. Your teaching ability is amazing.

[@noufalriyask1704]

Very usefull... Infromative.. Nice explanation👍🏻👍🏻..
I expecting more videos on power system protection scheme.. Relay.. And their setting etc
Upload videos frequently as you... 👍🏻 possible...

[@electricalchakra798]

Thanks a lot.
Actually what I faced that very few people are interested in protection schemes and theories, but maximum people are interested in testing related procedures.
That's why I had to upload videos with some basic testing and related topics.

[@johnreyalforque5577]

I can't understand the language spoken but very well explained and illustrated. Hope you can make a video explaining line-line fault current distribution of an unloaded wye-delta and delta-wye transformer. Thank you.

[@mayur9699]

Sir please make video on troubleshooting of CB control circuit

[@tapankumardas6279]

Excellent illustration about insulator, thanks a lot 👍👍

[@janardhanjagtap9082]

IEC 60034:is for rotating electrical equipment like Motor & Generators.

[@bodhisattwabhattacharya4312]

Well done !!

[@soumyadip1000]

Khub bhalo...any plan to cover generator testings ,which are carried out during overhaulings

[@bapunmishra5086]

Very Nice explanation

[@sivaprakashjayapal4719]

Good explained.... Thank you.

[@ganeshmahato4467]

Sir please make video on rotor earth fault

[@mangeshjalekar6086]

Gst Ust gstg mode for exa. T/F testing ke liye konse type testing ke liye use bataye jaise t/f HV to LV test karna hai aise differant types of testing mode use bataye

Why tan delta point is earthed?

[@arghyamukherjee8583]

Dada tan delta Ka 3 mode Kiu use karta h

[@ganeshachally4881]

It's very nice sir

[@electricalchakra798]

Thanks

[@piyushsardhara4437]

plz make a video on hipot test

[@ranjan1436]

How the frequency is lowered in the Tan dela kit? Do these machines use PWM techniques?

[@electricalchakra798]

Yes. It's PWM method.

[@ranjan1436]

@@electricalchakra798 how does it adjusts its frequency level?

[@HR-rp8pc]

सर more वीडियो please

[@syedrahman6399]

all over okay but sound problem

[@moumitamondal5188]

Sir where will I get to know the modes of tan delta
