Morning Waross
Many thanks for your input on this. Yes it definitely has a soft start system with thyristors and has a syncro speed of 1500 rpm. After another disappointing restart yesterday I'm now thinking it could be a bad generator so I'll megger test it this week and see how if it checks...
Following on from the above I'm fitting a new bypass contactor this week just in case the "very" old one is struggling to hold the contacts together (the old one was very noisy and still noisy after checking the shading ring and a general clean up) and I'm putting new capacitors in this week...
Morning Both
SPARWEB : No the OEM merged years ago and the engineer that erected the turbine is only very sporadically helpful. The controller is an old KK controller on a Nordtank wind turbine.I found this article on the web that sums up the problem (not the same soft starter though)but...
Hi Waross.......thanks for your reply.....sorry I dont have any schematics for the soft start circuit as we bought the turbine "used" :(
I should also add that its the bypass contactor that disengages / engages rather than the main grid contactor.Thanks Waross :)
Morning Everyone.
I've been running our 150kw wind turbine successfully for the last 8 yrs but after a completely different controller fault (voltage error on mains) seemed to "go away" after we changed the transformer board, upon restart of the turbine the following occurs
1. Normal start up...
