You do not use AC to megger a device, because the purpose of meggering is to measure the insulation resistance of the device. You use DC to do that. If you used AC, you would be unable to differentiate between insulation leakage and capacitance.
since the MICC cable the isolation between core is less as well as the outer sheath has probability of getting damaged during installation so meggering is important Any clarification mail to amal_elias@ymail.com
Depending on the equipment required for the substation,some of the tests are as follows: meggering,hi-pot testing,continuity checks,c.t. testing,relay testing,ngr testing, capacitance bridge test's on transformers.
The DC between windings is analogous to DC on capacitor plates. Windings, like capacitors, require time to charge up to the applied voltage, at which, there will be a constant current. Since Voltage / current= Resistance, the Megohm reading will change/increase until the windings are fully charged to a quiescent, steady leakage current. When current is at a stable leakage level, you will have an accurate reading. xfrmrman

The most basic answer is heat from friction, which is how the sun came into being.
We can find this in Zambales,Luzon ,Philippines Wecan also find this in Region 3 / Central Luzon
no.but we can win medallions by finishing an island.by doing this we get credits with which wecan buy new things in the store! thnx!!
What is the acepable rating on a #3 wire when meggering @1000v
No. The cable has capacitance, and an AC source would not be able to distinguish between capacitance and leakage.
tolerating others is respecting to others if we resprct each other wecan build the better world
Because the cable has capacitance, and an AC source would not be able to distinguish between capacitance and leakage.
becauge when we want a value store in then we use a variable and in which wecan store a value then this value use a hol the proram and we solved a problem but every funcation depand on a method.
