The

group

shaii

never

be

used

with

a

third

brush

generator

even

if

of

size

corresponding

to

the

generator

prescribed

above;

the

elimination

oi

the

third

would

not

change

things;

even

worse

it

wouid

be

to

connect

a

third

brush

generator

as

if

it

were

controlled

by

a

reguiation

unit.

The

reason

is

that

both

groups

and

generator

circuits,

mainly

the

fieici

coiis

of

the

generator,

that

are

so

reciprocaiiy

arranged

as

to

get

the

best

performance

for

the

whole

combination.
