2. Protection:
 Human “Memproteksi manusia dan peralatan dalam
operasionalnya di wilayah PLTGU Bekasi Power”
 Equipment

3. V1 > V2 > V3 > V4
Voltage difference in a spot to
another caused electron to move 
it caused electric shock
V1 V2 V3
V4

4. V1 = V2 = V3 = V4
ΔV = 0

V4

5.  Grounding
 Membuat bidang eq potensial dalam kawasan
semerata mungkin (Create different potential
(voltage) the same in all area)
 Down Conductor & Air Terminal
 Memasang penyalur petir (Install air terminal)
 Memanfaatkan ketinggian bangunan (Using tall
building)

6. Grounding Cable: BCC 50 mm²
Distance between grounding tap: 7-11m
