|A genarator is connected through a 20MVA ,13.8/138 KV
stepdown transformer to a transmission line. at the
reciving end of the line a load is supplied through a step
down transformer of 10MVA,138/69 KV rating .A 0.72 PU load
evaluated on load side transformer ratings as base
values ,is supplied from the above system for system base
values of 10 MVA and 69 KV in load circuit the value of the
load in generator circuit will be ...........
|In a power system we know that if the generated power is less
than the load then the frequency of the system is decreases.So
does this mean that total required load is delivered at alower
|I am getting above 60 V as open delta voltage against single
phase unit ICT at tertiary delta formed and ICT getting
trippped on NDR. ICT tested and found in order. PTs provided
on tertiary are tested and in order. what may be the reason?
