Hello everyone, I have researched for meaningful comparison between Mobil Volt Esso versus Nytro transformer oil online, and there seems to be no one doing this. Nytro has a long selection of transformer oil while Mobil Volt Esso has 35 and N36. We have had good experience using Volt Esso 35...

Davidbeach, the oil were previously used in substation power transformers and are now in barrels. Bacon4life can you please share a link of the setup you have to perform the reconditioning and reclaiming? Prc can you please give examples of the portable equipment that you mentioned? Thanks.

What do you mean Stevenal

Hi DTR2011, It's good to hear your team has a full set up performing this type of reconditioning. The oil I'm talking about have been tested for PCB level, and they all passed the level required in Canada. What is the equipment you use to process the oil? Our oil is in the 1000's of US gallons.

Hello, Has anyone here had experience with deciding whether to recondition (reclaim) used transformer oil or to junk it (sell it as used oil)? We performed oil quality test on the oil and they all fell under class 2 per IEEE C57.106-2006. The recommendation given for class 2 oil is to...

Hi everyone, I currently have a situation whereby the Tap Changer sometime leaks insulating oil through its breather. I have researched the Tap Changer to Main tank configuration from the product manual(how they are physically mounted), and noticed that they both have separate conservators. My...

Thank you all for your answers. Thank you LDGR. I did research online and found using a combination of asphalt coating and Alsan Flashing, together with meshing in between the joints will do the job. LDGR I think this is similar to your idea? Is there anyone here who has used these two...

Hello everyone, I am currently involved in some preventive maintenance projects. I would like to get recommendations concerning how to repair leaking switchgear roofs. I am planning on using a coating of rubberized mastic cement, to cover the whole switchgear top. I'm not sure if this is...

Hello fellow engineers and professionals, I am currently designing a solar PV system for a residential household that would be needing around 16.4 KWh/day (from my calculation of the household appliances wattage and the amount of hours each is used per day, and then compensated for the inverter...

Hey Zogzog, Yes, they are Federal Pioneer SACE breakers. Specifically, they are SACE Esafluor SF SACE Esafluor SFA. See this link for more on this: http://www05.abb.com/global/scot/scot235.nsf/veritydisplay/b0c4bd237b7ddd5dc1257ad8007ffc03/$file/MA_SFA(IT-EN)601174002-9710-PART1.PDF

Hello everyone, I am about to run a full maintenance on our SACE breakers and was wondering what the best lubricant is out there to be used for this purpose. I read online that synthetic grease are highly effective since they can withstand more variation in temperature and are durable. The...

Thanks to everyone for your advices. Fex32, I can resonate with your advice. During my past interviews, I have always thought I needed to learn something different (different from my resume) in order to participate in the interviews. Reading your comment gave me the feeling that I actually do...

Hello everyone, I am a recent electrical engineering graduate with three co-op work terms. I have a decent mark and good employer appraisals. I am both a theoretical and technical kind of person. I am a hard worker and have a strong drive to be successful. I have been applying for five months...

I have been using the R,C,8*,3 curves on COOPER form 6 recloser TCC settings and its been perfect so far. I will like to hear if there are better settings than this and also learn any experience you have working with these types of recloser. I have researched on the internet but most studies...

Hello, Thanks everyone for your help on my previous post. A great way to begin an engineering career!! I have been working with reclosers and, was wondering weither an intellirupter can provide a better job at protecting the upstream line with its ability to reduce the amount of fault current...

@Oldestguy I really appreciate your comment. What type of societies are talking about?

Thanks everyone for your advice

Hello, I am a new EIT and was wondering if I can get advice on how to adapt to work and relate to other engineers. I work for an electrical firm. I always focus on every tasks that I am given but new things always pop up at the end of the day and the work gets carried over to the next day. For...
