A
INTRODUCTION
With
a
few
eptions
,
the
Type
CAL
16
A
and
CAN
13
A
relays
are
Identical
In
construction
and
function
to
the
standard
secondary
network
relays
shown
in
the
Included instruction
book
GEl
-
13580
.
The
CAN
13
A
will
prevent
reclosure
if
the
source
phase
sequence
is
reversed and
the
network
phase
sequence
is
normal
.
The
principal
difference
af
-
fecting
both
relays
is
that
the
glass
cover
and
mounting
bracket
have been
removed
,
and the
relays
have been mounted
in
the
drawout
case
for
mounting
on
a
panel
.
Also
,
both
relays
have
2
ampere
holding
coils
in
the
reclose
circuits
,
Instead
of
the
0.3
ampere
coils
as
In
the
standard
relay
.
The
Type
CAN
13
A
relay
differs
from
the
Type
CAN
11
A
relay
In
several
points
concerning
physical
construction
and electrical
connections
.
The
only
change
in
function
is
that
it
is
designed
to
trip
at
approximately
0.005
ampere
,
current
transformer
secondary
current
,
in
phase
with
line
-
to
-
neutral
voltage
.
It
is
intended
to
be
used
for
tripping
when
the
only
reverse
power
flowing
is
the
magnetizing
current
of
the
associated
power
transformer
.
The
principal
differences
between
the
Type
CAN
13
A
relay
and the
Type
CAN
11
A
relay
areas
follows
:
1
.
The reclose
contact
is
on
the
left
and
the
trip
contact
on
the
right
,
facing
the
relay
,
on
the
Type
CAN
13
A
relay
.
This
is
the
reverse
of
the
Type
CAN
11
A
relay
.
2
.
The
main
control
spring
is used
to
adjust
trip
value
and
the
mechanical
restraint
Is
used
to
adjust
reclose
value
on
the
Type
CAN
13
A
relay
.
3
.
The
electrical
restraint
element
has
been
omitted
on
the
Type
CAN
11
A
relay
.
4
.
The
potential
coils
,
instead
of
being
connected
directly
to
the
network side
of
the
breaker
are
,
connected
to
a
resistor
combination
across
each
pole
of
the
associated breaker
.
This
last
feature
allows
the
potential
coils
to
be
energized
from
the
network
side
when
the
source
side
is
de
-
energized
;
or
from
the
source
side
when
the
network side
is
de
-
energized
.
When
the
breaker
is
closed
,
the
two
sections
of
the
resistor
com
-
bination
on
each
phase
are
effectively
in
parallel
and the
net
resistance is the
same
as
that
ordinarily
used with the
Type
CAN
11
A
relay
(
t
.
e
.
,
340
ohms
when
6054972
G
8
is
used
as
the
phase
-
shifting
trans
-
former
,
and when the
900
ohm
resistor is
used
in
the
phase
circuit
for
1.5
volt
reclosure
.
)
Therefore
the
tripping
characteristic is the
same
except
that
the
setting
is
0.1
%
instead
of
0.2
%
of
the
relay
rating
.
RECEIVING
,
HANDLING
AND
STORAGE
CO
The
relays
,
when
not
included
as
a
part
of
a
control
panel
,
will be
shipped
in
cartons
designed
to
protect
them
against
damage
.
Immediately
upon
receipt
of
a
relay
examine
it
for
any
damages
sus
-
tained
in
transit
.
If
injury
or
damage
from
rough
handling
is evident
,
file
a
damage
claim
at
once
with the
transportation
company
and
promptly notify
the
nearest
General
Electric
Apparatus
Sales Office
.
Reasonable
care
should
be
exercised
in
unpack
-
ing
the
relay
in
order
that
none
of
the
parts
are
injured
or
the
adjustments
distrubed
.
If
the
relays
are
not
to
be
installed
immediately
,
they
should
be
stored
in
their
original
cartons
in
a
place
that
is
free
from
moisture
,
dust and
metallic
chips
.
Foreign
matter
collected
on
the
outside
of
the
case
may
find
its
way
inside
when the
cover
is
removed
and
cause
trouble
in

The
one
ohm
resistor
in
parallel
with
the

(
Y

winding
of
the
phase
shifting
transformers
has
such
a
low
Impedance
compared
to
the

that
practically
all

A
passes
through
the

,
and
the

reading
is
equal
to
the

Since

the

The
trip
setting
should
be
checked
first
because
any
adjustment
of
the
trip
setting
also
affects
the
reclose
setting
;
whereas
,
the reclose
setting
can
be
adjusted
independently
of
the

and
should therefore be made last

except
at

Instant

TYPE
CAL
16
A
RELAY
The
Type
CAL
16
A
relay
Is
Identical
to
the
Type
CAL
15
A
relay
,
described
in
the
Included
Instruc
-
tion
book
GEl
-
13580
,
except
that
it
is
mounted
in
a
drawout
case
.
For
calibration
,
the
relay
should
be
connected
as
shown
In
Fig
.
5
.
The
normal cali
-
bration
of
the
Type
CAL
16
A
relay
Is
to
close
its
contacts
when
the
phasing voltage
(
on
studs
7
-
8
)
is
gradually
Increased
to
0.5
volt
,
leading
the
potential
voltage
(
studs
5
-
6
)
by
90
degrees
.
Adjustments
can
be made
as
described
in
GEI
-
13580
.
The
reclose
calibration
of
the
relay
can
be
changed
by
adjusting
the
mechanical
restraint
ele
-
ment
.
Turning
the
cap
of
the restraint clockwise
increases the
restraint and
therefore
the
reclose
calibration
.
Holding
Coils
Both
holding
-
coils
of
the
Type
CAN
13
A
relay
are
rated
2
amperes
.
These
holding
coils
can
be
checked
as
part
of
the
trip
and
reclose
adjustments
above
by
connecting
an
adjustable
resistor
in
the
contact
circuit
and
adjusting
the
holding
coil
circuit
to
2
amperes
.
As
soon
as
the
trip
or
reclose
con
-
tacts
make
,
the
sealing
armature
should
definitely
seal them
closed
,
and there
should
be
no
sparking
