1. introductionElectrical distribution systems, the system is stable or reliable. One of the things that make the system stable and high reliability, it is a system, it must not occur in the device brakes down. The brake-down occurs.Of insulation while the device is being used as the cause.The major causes of damage that ron and a system that is connected to the device, it will be corrupted.Followed by the same. Insulation is an important part in preventing the occurrence of braking down in this research study.Research on the occurrence of specific possible brake down insulation, insulated only by gas gas air is used [1], [2] researchers design.Electronic measurement and trot to the batch analysis based on IEEE standard braking down Std 4 IEC 60060, 1995 –.-1.IEC 60060-2 and [3]-[4] as follows: A pointed electrode electrode trot trot trot a needle electrode and electrolyte trot round.Half-round Design Kit based on the standards of the IEC 60060-1, IEC 60052, and IEC 60156.[4], [6], [7] which has examined damage to the surface electrode and trot after the brake voltage occurs in a trot down the needle electrode. Scanning electron microscope (SEM).
