Answer / hardik vyas
A Thumb Rule for acceptable IR value of vable is (Rated
KV+1)M Ohm. i.e if you have 11 KV cable then accepted
value vill be 11+1=12 M Ohm

Answer / emmanuel
Thumb rule for IR value of a cable as we all know in (rated
KV +1)M ohm . Thus for XKV cable the reated inulation
resistance value is ( X kv +1) Mohm

1. How many types of mangers? 2.How many types of capacitors? 3.pls tell me normally types alternator problems?
why always out of the 3 phase(RYB) of supply, in Y phase w.r.t the voltage is higher? on R & B phase the voltage will be lower as compared to Y phase?
IF I KNOW THE AREA OF CROSS SECTION OFTHE WIRE , WATTAGE OF THE LOAD ,VOLTAGE SUPPLY WHAT IM GIVING TO THE LOAD AND ALSO POWER FACTOR OF LOAD ....... SO GIVE ME FOR WHAT AMOUNT OF CURRENT I SHOULD USE WHICH TYPE OF CABLE?
Is there any calculation to find unknwon(unferroled) phases R Y B in alternator,3 phase motor anybody shoot my problem. how can we notice this is the respective phase?
how the transformer stables out zone faults? Because we use non directional O/C relays .Is there any special considerations are taking into account to overtake this?
1) Can anyone give me a typical value for Insulation Resistance of 11kV xlpe cable? 2) How much will the IR value decrease per KM of cable length added?
