Q and A RFQ 36C26024Q0780.pdf

1) we need to know what type of oil the transformers have so we can include supplying that oil to the jobsite for technicians to top-off. All transformer oil is different pricing wise. Also, I know it says in the SOW that the warehouse is not expecting to shutdown the transformers, but in order to top-off the oil the transformers must be de-energized. Please advise?

Answer: Mineral oil is the type referred to us by our typical service provider

“Transformer Services, Inc.” and is listed in out SPCC plan. Thank you for thoughtful question on shutdowns. If a shutdown is needed, we will accommodate it. But an action plan is required to be submitted 3 weeks prior, as the facility has to complete various memos.

2) Could you please provide the following detailed information about twenty‐eight

(28) liquid‐cooled medium voltage transformers:

What Type of Transformer?

Answer: Step down oil transformers from 12,450 VAC to 208 VAC, though two (XFMR “M” and “P”).

What Type of Liquid: Type of liquid used (e.g., mineral oil, silicone oil, ester-based fluid)

Answer: Mineral oil is the type referred to us by our typical service provider “Transformer Services, Inc.”.

Volume of liquid required (in liters)

Answer: Responder hesitates to answer this, as it seems to ask the volume of each transformer.

Offeror to apply the language of the SOW to his/her offer; i.e. top off all transformers as needed, but assume 2 will need oil replaced. If they end up not being needed, VA will received the offer amount back as a credit per the VAAR.

Specific brand or product name of the liquid, if applicable

Is the liquid provided, or do we need to supply it?

Answer: Contractor provides all labor and materials. Manufacturers recommendations supersede “industry standards” regarding brand of liquid.

3) Are previous oil test results available for all transformers?

Answer: They are available for some. Please see attached tests for 2010 and 2016.

We have newer transformers that have been installed since the last testing/service occurred, however.

4) What are the sizes of the 2 transformers that need oil replacement?

Answer: Please see answer 2.

5) What is the driver necessitating oil replacement in 2 transformers?

Answer: There is no specific driver, and it may not be needed. But it is easier for VA to have that in the offer and get the credit back than to add it as a change order.

6) Can you please provide a clear picture of each nameplate which will show what type of cooling liquid each transformer has and approximately/ballpark number of how much each one might need to be topped off with?

Answer: In lieu of a nameplate, would you kindly refer to the tabulated information given in answer 2. As for oil top off, the VA would not have that information, nor would we have control over how much oil the sampler removed which had to be topped off afterward. Past assumptions from our typical servicer indicated 1 gallon per transformer.

7) Line item 0002 says to replace cooling liquid in two transformers. Can you please provide a clear picture of the nameplate which should show the type of fluid used and how many gallons it contains?

Answer: In lieu of a nameplate, would you kindly refer to the tabulated information given in answer 2. We do not know which of up to 2 would need liquid replacement. In fact, it is unlikely that they will. But it is easier for the VA to have that assumption so it is covered.

gii New insulation with a high degree of mechanical strength will typically have a Degree of Polymerization (DP) of 1000-1300. “Middle Aged” paper is approximately 500 and paper with less than 250 is in its “Old Age.” Severely degraded insulation with a DP of 150 or less will have very little mechanical strength and may result in a transformer failure. The above estimations are based on a study by Chendong of GSU transformers filled with mineral oil.

Estimated Average Degree of Polymerization (DP): 637

Estimated Operating Age of the Equipment: 19.2
