Phase Shifting Transformers
(OP)
Any experience with specifying a large (50MVA) phase shifting transformer. What computer tool or model was used to develop the phase angle shift requirements? Who was asked to bid?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Phase Shifting Transformers
In ANSI regions, one reference may be IEEE Std C57.135-2001 …Application, Specification, and Testing of Phase-Shifting Transformers
RE: Phase Shifting Transformers
A partial table of contents is 1 Scope, 2 Purpose, 3. Definitions, 4. Application and theory of PSTs, 5. Service conditions, 6. Rating data, 7. Construction, 8. Short-circuit characteristics, 9. Control system, 10. Testing of PSTs.
RE: Phase Shifting Transformers
Can i ask as the your desired use for this type of transformer?
RE: Phase Shifting Transformers
jmalouf: what program was used to analyze your system and who was the manufacturer?
RE: Phase Shifting Transformers
I am looking for more info on Phase-Shifting Transformers(132kV, 100MVA).
Thanks to 'busbar' for the folowing reference.
'IEEE Std C57.135-2001 …Application, Specification, and Testing of Phase-Shifting Transformers'. I have orderd the document.
Specifically I need the following information.
- A list of manufactures.
- A list of sites where large PSTs are in service. I want to visit a few installations to look at the operational issues. Contact details of people from these utilities will be very useful.
- Any other documentation or references will be appreciated.
Thank you.
Best Regards.

I have recently obtained budgeary quotes from ABB, and Alstom. Both site experience on their web sites.
Utilities have numerous units in service. PSE&g has two right in northern NJ. They are old technology. Utilities usually get them with same input and output voltage levels to regulate power flow in tansmission circuits. For a good review of the various configurations of the windings and tap changers see IEEE Trans. on Power Delivery, Vol 13, No. 2, April 1998 by A. Kramer & J. Ruff. An interesting paper on modeling a PST is in IEEE Power Eng. Review,Feb. 2001, pg 51.
