In recent times, gsu transformer has become increasingly relevant in various contexts. GSU Tap changer control strategy - Review | Eng-Tips. Dear all, I went through the forum to see the input regarded the control strategies and installation requirements for the generator ste-up unit transformer tap changer and I found some indications. However I would appreciate if anyone can provide some literature regarding this topic whether in... Doble Tests of Power Transformer | Eng-Tips. Building on this, are Doble tests effective in evaluating health of GSU transformer windings?
Does a transformer need to have its oil drained prior to performing a test (Doble or Megger) to focus on winding insulation, since oil would act as an insulator? Building on this, gSU Transformer | Eng-Tips. Hello, I am putting together a specification for a 115/2400 GSU transformer and I was wondering if anyone on here may know if this type of transformer should follow IEEE Std. C57.116-2014: IEEE Guide for Transformers Directly Connected to Generators?
In relation to this, also, what is the difference between normal... Furthermore, generator grounding & protection with a wye-wye transformer | Eng-Tips. Given a generator 1.6MW 480Y/277V 60Hz and a GSU transformer with primary and secondary windings wye connected, neutral internally tied and solidly grounded. In this context, what is the best method of grounding and minimum protection (relaying) necessary for the generator? Generator + GCB + GSU Transformer + 2 UAT reliability | Eng-Tips.
Hello, I have seen a tender for a power plant where the single-line diagram shows Generator + GCB + GSU Transformer + 2 UAT. The only way of feeding generator auxiliaries is through the UAT, as no station transformers of MV lines are available. The connection between Generator + GCB + GSU... Can a Generator Stepup transformer that has nearly the same ratio of the input to output voltage be used in place of a damage one if the MVA rating is high enough? The original one was 300 MVA, 15KV delta- 230KV Y. Can a 445 MVA, 22KV delta - 345KV Y transformer be used instead?
Sizing of a GSU | Eng-Tips. From another angle, you need to look at the generator capability curves and nameplate ratings. Size for at least the highest MVA rating, plus a little extra. You don't want the output capacity of an entire power plant restricted by your generator transformer.
I doubt anyone ever got fired for slightly oversizing the GSU. Transformers are MVA machines. Unit Differential Protection (87U) | Eng-Tips. Our new design has a generator(296MVA), with GSU transformer (305MVA) and unit auxiliary transformer (24MVA) directly connected to the generator terminal.
With the plant unit differential protection(87U), I understand that one set of CT should be at the HV side of the GSU and the second set... GSU Transformer - Specifying (generator side) voltage rating.
