SAFETY

Earthing is important thing in one of parameter safety. In each plant the earthing

must be separated in a few group, likes

22

must be separated in a few group, likes instrument ground, equipments ground,

transformer ground, especially instrument ground need to be ascertained separated

from others

Our Parameter grounding, they are:

-PE (Protection Earth) = 3 ohmGround for Electro motor, Cable trays, Piping,Equipment & InternalTank

-LE (Lightning Earth)= 3 ohmGround for Lightning Arrester

-FE (Functional Earth) = 3 ohm

3

-FE (Functional Earth) = 3 ohmGround for Transformer

-IE / IG (Instrument Earth) = 1 ohmGround for Instrument & sensor

-GG (Ground Grid) = 3 ohmGround for columns / building

RELIABILITY

In installation, power cable need to be disjointed with instrument cables and placed in separate cable ladder, which it’s

44

placed in separate cable ladder, which it’s differentiated colour.Our standard :- Blue colour for instrument and sensor cables also for cable ladder

-Grey colour for power cables also cable ladder

Election of cable ladder better than cable tray since at cable tray can happened dust heaping and sometimes mouse likes makes den in cable cable tray.

STANDARDIZATION

Need to be made one uniformites for E&I engineer in the case of overload setting, especially at motor starter since often

88

especially at motor starter since often overload setting too higher so that can

burning motors

Stater motor (Star, Delta / SD)

Stater motor (Direct On Line / DOL)Current setting O/L = I motor X 0.8

9

Stater motor (Star, Delta / SD)In = I motor : 1.73 Current setting O/L = In X 0.8

TRAINING / MEETING

In future need to be continued meeting E&I engineer like now our do it once in one year

and need to be arranged the suppliers to

1010

and need to be arranged the suppliers to visit our plant for problem solving together

our E&I engineer

MANAGEMENT / ORGANIZATION

To form a solid team for E&I required the coordinators in Indonesia, they are :

1111

1. E&I HEAD : COR VERKERKE2. INSTRUMENT & AUTOMATION : CHIN WAY TONG3. ELECTRICAL & POWER DISTRIBUTION : HALIM

SUJATMIKO & ANTONI SITEPU

The coordinators required support fromthe E&I units and also of course supportfrom management
