Subject: RE: LV Talks: Draft Informal survey of small, low-voltage manufacturers 

Thanks for working on this. I look forward to seeing the Navigant questions.

I understood the main objective was to understand how these small businesses will be impacted by

higher efficiency standards. We need to know a little about their businesses to get a clear picture of the

impact. However, all the detailed questions listed by Richard may take energy away from getting to the

real issue of whether these small facilities and/or businesses will be in business at EL0, EL1, El2, etc.

Good luck Rob. I look forward to seeing your questions and preliminary findings.

Thanks. Good news, Rob. Could you send around the list of questions you are posing?

Hi Richard,

We have begun calling small manufacturers already.  We have a list of questions, similar to yours below.  

We’ll be compiling the information that was requested (to the extent that we get quality feedback) over

the next week or so.  

Thanks,  

Rob

Mike and team, 

As you may recall, we all agreed last Friday to send out and/or call the small manus in the low 

voltage space to pose a series of questions we discussed in meeting generally. The plan was to 

draft a brief questionnaire and circulate that questionnaire internally before sending out/calling 

so that stakeholders could make sure their key questions are addressed. 

I realize everyone is stretched for time at present, so in the interests of expediting process I offer 

the following queries that I believe more or less capture the kinds of things we talked about 

needing to find out. This draft is offered just to get the discussion going. I have no pride of 

authorship and I'm sure your team can refine these questions to make them more artful, precise, 

relevant. 

Main thing is we need to get the questionnaire finalized and presented to the companies so we 

can get answers ASAP. 

I know Andrew DeLaski and John Caskey expressed an interest in getting these sorts of 

questions answered, so I will invite them to weigh in as well with any suggested changes. If we 

don't need all this information, by all means let's eliminate any questions that aren't needed. 

Once the questions are settled, we need to discuss manner and timeframe for presenting them -- 

through written questionnaire or phone calls. 

Best, 

Richard 

Draft questions 
1. What is your total annual sales volume, and total employment? 

2. What is your total annual sales of transformers? 

3. What volume of sales (by $ and/or MvA) are covered products [Navigant to supply 

definition of what that is]? 

4. What proportion are exempt products [Navigant to supply list of exemptions]? 

5. Do you ship low-voltage transformers that exceed the current efficiency standard of 98% 

efficiency (in the case of Design Line 7, which are 3 phase transformers from 15-150 

kVA) or 98.60% efficiency (for Design Line 8 which are 3ph, 225-1000 kVA)? If so, 

what efficiency levels do they reach and what is the volume of sales at each higher level? 

6. Do you outsource any of your cores for covered products? If so, what proportion of cores 

are outsourced? 

7. If you make your cores internally, please answer the following questions: 

o what core design do you manufacture (e.g. butt-lapped, step-lapped) 

o what core steels do you employ? If more than one, please indicate the percentage 

mix of steels. 

o Do you have utilize mitering techniques currently? 

o Do you make wound cores currently? 

o If hypothetically the industry were to move to a higher efficiency standard for 

low-voltage transformers at which efficiency level (EL) (see table below) would 

you find it expedient to convert to mitering or wound core designs (please 

specify) and what would the total and per unit costs of conversion be? 

 

Current 

Standard EL 1 EL 2 EL 3 EL 4 EL 5

Design Line 7 (DL7) 3ph, 15-225 kVA 98.00% 98.47% 98.60% 98.60% 98.80% 98.93%

Design Line 8 (DL 8)3 ph, 225 - 1000 kVA 98.00% 98.47% 99.02% 99.25% 99.32% 99.44%
