4.4 Admissible voltage drop

4.4.1 Voltage drop calculation formula

The voltage drop is calculated from the following formula;

- Single-phase voltage drop : Vdrop = 2 × L × I (Ra cosθ + X sinθ )

- Three-phase voltage drop : Vdrop = 3 × L × I (Ra cosθ + X sinθ )

- Motor start voltage drop : Vdrop = 3 × L × ILRC (Ra cosθ LRC+ X sinθ LRC)

where L = feeder length in km

Rc = conductor resistance of cable in D.C. at 90℃(ohm/km)

Ra = conductor resistance of cable in A.C. at 90℃(ohm/km)

X = core inductance (ohm/km)


of 11


I = rated current of electrical consumer to be connected (A)

ILRC = Locked rotor current (A)

cosθ = power factor of electrical consumer to be connected

cosθ LRC= L.R.C power factor

For R and X values, refer to Attachment #9

4.4.2 Voltage drop limitation considered are as follows.

Feeder Voltage Drop

From main switchboards to consumers during normaloperation 5 %

Motor cables at full load 5 %

Motor cables from switchgears to motor terminal duringstarting 15 %

Lighting and small power cables (including AC, DC UPScircuits) between secondary panel and the furthest lightingfixture/small load.

- When secondary panel is located in unit 3 %

- When secondary panel is located near the maindistribution panel in substation 5 %

AC, DC Uninterruptible power supplies main power cablesbetween batteries and main equipment cubicles 1 %

4.5 Short-circuit current

The minimum conductor size for short circuit current is calculated as follows as

per clause 434-03-03 of IEE WIRING REGULATION 16th edition 1991.

kItS ×

=

S = nominal cross sectional area of conductor in mm²

I = The value of short circuit current in amperes, expressed for a.c. as the

r.m.s value.

k = 143 for HV cables insulated with XLPE

t = duration of short circuit (sec)

0.25 sec (12.5 cycle) for HV circuits

Note 1. 0.25 sec (12.5 cycle) for HV circuit is based on the following

fault clearing time.

Breaker : 5 cycle (0.1 sec)

Instantaneous relay : 1 cycle (0.02 sec)

Safety margin : 6.5 cycle (0.13 sec)

Note 2. 0.1 sec (5 cycle) for fused contactor circuit of HV motor feeder.

Note 3. For the cables routed in classified hazardous area, it shall be

ensured that surface temperature of cables does not exceed

the given temperature class of the hazardous area (T3=200

deg.C) during overcurrent or short circuit fault conditions. This

may be ensured by close consult with cable manufacturer

verifying the temperature propagation speed from the copper

conductor to the outer surface of cables via insulation, armour

and outer sheath in terms of fault clearing time by protective

devices such as fuses or relays.
