Tracking Phenomenon (Solution! Eliminate any harmful leakage current protective devices residual current with 300 mA)
1. There are pollutants and sticking on the surface of insulation
Leakage currents (residual) flow through the small part that pollute and / or with high humidity
2. Small sparks arise during the drying stage
1. There are pollutants and sticking on the surface of insulation
Leakage currents (residual) flow through the small part that pollute and / or with high humidity
2. Small sparks arise during the drying stage
The dry part can no longer withstand voltage, nascent small electric sparks on the surface. Sparks Centre has a very high temperature > 10 000 C
3. Certain places there pengkarbonan
These places occur after periods of warming pengkarbonan ; started slightly damaged insulation material
4. Leakage current to flow again during the next sticking
During the period of the next sticking, flow gradually enlarged to flow through the damaged surface
5. During the subsequent drying stage, resulting spark new. The number of electric sparks increased, pengkarbonan surface and causing widespread damage to an increasingly severe
6. Damaged surface increases the longer the.

The bits of insulation resistance decreases, the flow grows in each cycle.
7. After a certain time to burn insulation materials
When the leakage current becomes large enough, electrical sparks that occur are strong enough to burn the insulation material
