Answer / ankamsreekar

by counting the no of insulators in the string insulator.

Answer / ankamsreekar

in continuation with my first ans the no of insulators for
different voltages are given below

voltage suspension tension or dead-end
KV assembly assembly

11 1 1
33 2 3
66 5 6
132 9 10
220 14 15
400 21 22

Answer / balu

by counting the no of discs in the suspension type
insulator,each disc supports the voltage of 11KV

Answer / noufal p

The no of insulators for a particular HT voltage can be found out using the following method,

No of Insulators = ((Phase Voltage )/ 11KV )+ 2 );

because, insulators are calculated for phase voltages, one disc insulator can carry almost 11KV. One or two extra insulators can be provided to reduce the voltage stress of each insulator

Answer / priyanka

by the no of lines per phase

can I connect 25KvA stepdown transformer(RYB-440V,UVW-240V) to the output of 15KvA,3-phase online UPS(440V phase to phase)please brief.
