Dear All
What is the difference between 22oV 50HZ & 110 V 60HZ ? which is the cheaper between the two ?
If we have 220-240 V 50HZ systeem & the frequency raise more than 50 HZ what's happen to the equipments & what's behavior of the system !!!!!!
Pls. Check & Advise
Thanks lot...
Kindly inform me the relationship between GMD & GMR, How can I calculate GMR for ACSR Conductor size 120/20???
Where:-
Strands - 26/7
D.cm – 1.55
GMD m - 1.26
Cheers
Dear all
I’m just working with new software for analysis & distribution net works call SYME
(CYMDIST & CYMTCC), during the collection of data base as required by the software, they asked for GMR of conductors & cables,
Please advice.

Yes , u are right tonyjony it must be provided by manufacturer & they listed at the name plate for each transformers & the value of Z% different from one transformer to another , our typical value in Iraq is 4% greater than that is not acceptable , What I understood from waross that we...
Dear Waross
Thanks lot for your assistance, would you please explain to me the practical method to calculate Z% for 11/0.4 KV step down transformer 1000KVA, what is the acceptable limits for Z%!!!!
Cheers
Dear all
Kindly inform me regarding the voltage impedance calculation of 11 kV transformers, is it the important factor to write it down at the name plate???????
