What are the costs of an AVR?

Hello all.I am an electrical engineering student and I was wondering if anyone can give me some lights about the costs associated with an Automatic/Electronic 32-Step Voltage Regulator (for power distribution application...)I mean all the costs associated with it, but separetly:1- Acquisition cost (average or price range...)2-Installation cost (average, considering normal conditions...)3- Operation cost, including cost of power losses and maitenance costs (both average values...)4- Expected operation lifetime...? (in years)Just to have an idea. This information is for a university task.

Regards and thanks in advance.

Philippe Mertens • Hi David,

I am familiar with following AVR relays:- TAPCON 230, 240 and 260 from MR

- REG-D and REG-DA from A-Eberle, - SPAU from ABB- KVGC 202 from AREVA- Supertapp / RVM5 from VA-Tech Reyrolle with RTMU1 moduleFamiliar means I was involved in the transformer design and as an option, I ordered them, programmed and assisted installation. Sometimes I went on-site for modifications, error's, customer assistence.

I've seen prices of the single relays, the complete build-in relay panel prices and the total package prices including FAT testing, shipping, on-site installation.and on-site testing. I'm not putting commercial information on linked-in but you can mail me ph.mertens@telenet.be Of course there are no operation costs and I'm not sure how you want to calculate them.

As a small remark, all these AVR's are electronic but there's a huge difference in analog relays and digital relays. The number of steps does not change the price. I guess you must be a bit more accurate on functionality:- suited for transformer parallel opereation yes or no.- If yes, which operating principle master-follower or minimum circulating reactive current- suitable for step-by-step operating principles?- Are there OLTC blocking functions in case of undervoltage, overvoltage, overcurrent- Is there an overvoltage monitoring- Is line-drop compensation possible- programmable dead-band?- programmable time delay

One cost factor that also needs to be considered is the extra equipment cost like 1 VT, 1CT (in case of LDC) one tap position output in the OLTC motor drive in case of parallel operation with master-follower.
