Anyone familiar with Neplan? I got a 3 windings transformer rated at
1. 7.6/6.8/0.8MVA,
2. 18/11/0.415kV,
3. Uk(H/X)=12% to 6.8MVA base
4. Uk(H/Y)=5% to 0.8MVA base
5. Uk(X/Y)=7.5% to 0.8MVA base
May i know how to translate this to
Rated power in MVA.
12: primary-secondary,=6.8?

My 11kV Busbar feed by 15/11kV Delta-Start Transformer, Star side Earthed by NER. At the same time another standby diesel Genset connected and neutral point earthed by NER as well. To operate both parallel, what should i set for my Diesel Genset's EarthFault Protection to avoid spurious tripping...
I got my generator data as below but not sure which value to use as Gen. Positive Sequence Reactance.
1.Xd (unsaturated)=2.46pu
2.X'd (unsaturated)=0.247pu
3.X''d (unsaturated)=0.188pu
4.X'dv (saturated)=0.225pu
5.X''dv (saturated)=0.137pu
what is the difference between saturated direct axis...
I got a 128.7kW,50Hz,415V delta connected motor with "Trickle voltage heating" method installed. The motor totally enclosed, have very little room available for installation of heater. The heating system consist of Single phase 500VA,415/24VAC transformer connected to two of three winding. A 16A...
