Cause analysis
PEA change position of 22 kV. Transmission line for installation 115 kV Transmission line.
PEA will installation 115 kV. Transmission line on outside of Riser pole. So we must be moving 22 kV. Transmission line on
outside of Riser pole to inside of Riser pole.
1. Close circuit in disconnecting switch (Position A) for connect Line 2 to Panasonic
2. Open circuit in Load break switch (Position B) for moveing 22 kV. Transmission line from Line 1 to New line 1 position.
3. Close circuit in Load break switch (Position B) for connect New line 1 to Panasonic
4. Open circuit in disconnecting switch (Position A) for disconnect Line 2 to Panasonic
*Remaek : Because of Line 2 used for support Amper Ubonratana before come to support Panasonic. So the Voltage of electric is
not enough.
