(2)

Voltage drop in stub anode feeder.

E = IR

where

I

=

1.02 A

R

=

0.032 ohm

E

=

1.02 x 0.032

E

=

0.033 V

(3) Voltage drop in anode suspension conductors. Estimated

length 50 feet, No. 2 AWG (refer to Table 10), 0.159 ohms/1,000 feet:

R = (50/1,000) x 0.159 = 0.008 ohm

E = IR

where

I

=

1.02/10 = 0.102 A

R

=

0.008 ohm

E

=

1.02 x 0.008

E

=

negligible

(4)

Voltage drop through stub anodes:

E = IR

where

I

=

1.02

A

R

=

9.54

ohms

E

=

1.02

x 9.54

E

=

9.73

V

(5)

Total voltage drop in stub anode circuit.

E

= 0.033 + 9.73

I

E

= 9.76 V

T

(6) Since the stub anode voltage is below the 45 V calculated

for the main tank anode circuit, the necessary current adjustment can be

accomplished through a variable resistor in the stub anode circuit.

q)

Stub anode circuit variable resistor:

(1) Criteria for variable resistor. The resistor should be

capable of carrying the maximum anode circuit current and have sufficient

resistance to reduce anode current by one-half when full rectifier voltage is

applied to the anode circuit.
