Hi all, I have simulated (both in software and experimentally) inter-turn winding short-circuit fault in a single-phase transformer (working as a stand alone unit). I have the following observation but don't know the reason behind it:- The fundamental component in the no-load current is...

Hello Carl Pugh, Thanks for your suggestion. I would like to ask a question here - by 'resistors' and 'inductors' do you actually mean core-loss resistances and magnetizing inductances ? Thanks, Shantanav

Hello Sir Askalot, Purpose of my simulation - Trying to simulate the transformer under healthy condition and get current waveforms as close as possible to my actual lab-transformer. So, I am trying to model the core as similar as possible to the actual specimen I have. Yes, I incorporated...

Hello Gerbi, Thanks for your suggestion. Yes, I followed your steps. Actually, I created a new material. Firstly, I got a BH curve for hot-rolled low-carbon steel from the Sawhney machine design book and incorporated that into the material (since my transformer's material is hot-rolled...

Thanks Gerbi for your response. Ok, I will shut down the settings for eddy-currents and concentrate only on the core loss settings. So, I purchased this transformer from the manufacturer and at present I do not have the specified P (W/kg) vrs B (T). What I do have is a curve for Magnetizing...

I am designing a 2D model of a three-phase core-type transformer in ANSOFT MAXWELL 14.0. While doing so I have encountered a strange problem. Start of the problem:- While designing the transformer, I wanted to incorporate core losses. So, I did the following steps:- Excitations -> Set...
