Power Plant Engineering By G.r.nagpal [mqeg3mz2gol5] E.H.V. lines are now in operation in Europe, USA and Canada and oplrate at 330 kV, 400 kV, 500 kV and 700 W. Still higher voltage 1000 kV level are in the experimental stage. In India there is no E.H.V. line so far but it is hoped that soon such lines in the form of Super Grid will be developed.
What is HIPOT Testing (Dielectric Strength Test)?· Other examples include identifying a pinhole defect in insulation or finding an enlarged solder footprint. As per IEC 60950, The Basic test Voltage for Hipot test is the 2X (Operating Voltage) + 1000 V The reason for using 1000 V as part of the basic formula is that the insulation in any product can be subjected to normal day-to-day transient over voltages.
