TECHNICAL INFORMATION
7. What voltage classes of NOVA-TS reclosers are
available?
Currently, NOVA-TS reclosers are available at the
15 kV and 27 kV voltage classes. The maximum
design voltage of the 27 kV recloser is 29.2 kv.
11. What is the BIL of NOVA-TS reclosers?
15 kV NOVA-TS - 110 kV BIL
27 kV NOVA-TS - 125 kV BIL
12. Is NOVA-TS included in the Kyle Classic
Program?
Not yet. But because Kyle adds new products to the
Classic program each year, look for NOVA-TS to be
included in the future. See Bulletin 91005 for Kyle
Classic details.
POWER INFORMATION
13. Where does the NOVA-TS mechanism gets its
power from?
The magnetic actuator in each recloser mechanism
derives its operating power from the energy-storage
capacitors located within each unit. These capacitors are charged by two 12-volt lead acid batteries
located in the Form 5/TS recloser control.
14. Where does the Form 5/TS control gets its power
from?
As with other Kyle microprocessor-based recloser
controls, a control power transformer is needed to
provide power (120 Vac or 240 Vac) to operate the
Form 5/TS control.
15.When must the batteries in the Form 5/TS control be replaced?
The 12 Vdc control batteries have a life expectancy
of 4 to 6 years. It is recommended that the batteries
be replaced after 4 years. A battery test is included
as standard in the Form 5/TS control.

9. What is the rated continuous current of NOVATS reclosers?
NOVA-TS reclosers can be specified with a 400 amp
or 800 amp continuous current rating.
RECLOSER INFORMATION
16.What mechanism is used in the NOVA-TS
recloser?
The NOVA-TS recloser relies on the same low-energy
magnetic actuator mechanism used in other NOVA
products. The magnetic actuator provides accurate,
reliable opening and closing operations, including
any required operations, without ac presence.
17.Is there an OPEN/CLOSE contact position indicator?
10. What is the rated symmetrical interrupting
current of NOVA-TS reclosers?
NOVA-TS reclosers can be specified with an 8.0 kA
or 12.5 kA symmetrical interrupting current rating.

Each phase of the NOVA-TS recloser has a large
visible OPEN/CLOSED position indicator located on
the side of the sleet hood.
Frequently-Asked Questions
18. How is control lockout indicated?
Each phase has its own set of status LED’s on the
Form 5/TS control front panel. The CLOSED red
indicator illuminates when the control senses the
recloser mechanism is in the closed position. The
OPEN green indicator illuminates when the control
senses that the recloser mechanism is in the open
position.
The green LOCKOUT indicator also illuminates
when the recloser is open and a reclosing sequence
is not in progress or when the lockout handle on the
recloser mechanism is in the down position.
19. Will the yellow manual operating handle move
to the down position upon sequencing to lockout?
No. The yellow manual operating handle is only
moved to the down position via a hotstick during a
manual opening operation. If the control sequences
to lockout, control lockout will be indicated on the
the status LED’s on the front panel of the Form 5/TS
control and the contact position indicator will indicate
the recloser is OPEN, but the yellow manual operating handle will remain in the up position. Since the
NOVA-TS includes a SCADA accessory option, the
yellow handle must remain in the up position to all
supervisory closing. Standard industry practice is to
disable all closing (both local and supervisory) when
the yellow handle is down. Therefore, the yellow
handle on the NOVA-TS recloser remains up while
in lockout to allow for supervisory closing functions.
20. Can you manually close the NOVA-TS recloser?
No. Pushing the yellow operating handle to the up
position will not close the recloser. All close operations are initiated by the Form 5/TS control. The yellow operating handle must be returned to the up
position for the recloser to respond to a close signal
from the CLOSE push buttom or from supervisory
control.
21. Does the NOVA-TS recloser have SCADA capabilities?
Absolutely. Just as the Form 5 control was designed
with line automation in mind, the Form 5/TS control
continues with dual communication ports, automation packages, and an updated database for easy
implementation.
APPLICATION INFORMATION
22.How do you make sure the three separate units
open together (in certain operating modes) when
you do not have them mechanically ganged?
The Form 5/TS control continually monitors the open
and closed position of the NOVA-TS recloser to
ensure each phase is in its proper state. Actual limit
switches are directly coupled to the mechanism and
monitored by the control. Since the units are not
mechanically ganged, the Form 5/TS control artificially gangs them for monitoring purposes.
23. Why are the trip settings all the same for three
separate reclosers?
Typical utility operating practice is to balance the
loading as much as possible on a three-phase distribution feeder to minimize the power delivery losses.
24.Explain phase and ground trip. Why do they
operate differently?
B r i e f l y, phase trip corresponds to the actual load
current through the conductor while ground trip is
the unbalance of the three-phase currents. Ground
tripping will trip all three phases below the phase trip
minimum trip value since ground tripping can be the
result of any unbalance on the system, including
load unbalance, one or more open phases, or low
magnitude ground faults.
25.Can you have three separate phase and ground
trip settings?
The use of multiple profiles can be used for multiple
settings, but typical utility operating practice is to
balance the loading as much as possible on a threephase distribution feeder to minimize the power
delivery losses.
26. When in Mode B or C, why do we lock out all
three phases on a ground current fault?
In all modes, not only modes B and C, ground sensing
remains the same. The performance of tripping all
three phases for low magnitude faults for modes B
and C is based upon the unbalanced current for a
three-phase system. However, this does not mean
that all ground faults will always trip three-phase. As
an example, if a recloser is located where the available
phase-to-ground fault is 8,000 amps and the ground/
phase minimum trip level is set at 200/400 amps
r e s p e c t i v e l y, any ground fault from 400 amps to
8,000 amps will trip only the faulted phase, even if
the phase time-current curve is faster than the
ground time-current curve. It is only in the narrow
band from 200 to 400 amps where a ground fault or
system unbalance of any kind, not distinguishable
by fault current magnitude, will trip all three phases.

NOVA-TS Recloser and Form 5/TS Control
27. How does the control know all three units are
open/closed?
The Form 5/TS control continually monitors the open
a nd c los ed position of the NOVA-TS recloser
through actual limit switches directly coupled to the
mechanism.
REFERENCE INFORMATION
28. What TCC Curves are available for the NOVA-TS
control?
The same TCC Curves available for the Form 5 control are also available for the Form 5/TS control. See
Reference Data R280-91-34.
29. Is there any recommended maintenance of the
NOVA-TS recloser?
Because NOVA-TS reclosers are applied under
widely varying operating and climatic conditions,
service intervals are best determined by the user
based on actual operating experience. However,
N O VA-TS s olid-insulated vacuum interrupting
reclosers should be inspected every six years.
30. What control is the NOVA-TS recloser designed
to work with?
The NOVA-TS recloser and Form 5/TS control must
b e us ed t ogether. The NOVA-TS recloser is a
unique three-phase Kyle recloser because it is
designed to work solely with the Form 5/TS control
due to its triple-single control functionality.
31. Can a NOVA-TS recloser be used with an existing Form 5 control?
N o. T he Form 5/TS control has been specially
designed for use with the NOVA-TS recloser. The
standard Form 5 control does not have triple-single
control functionality.
32. Can I use a NOVA1 recloser with a Form 5/TS
control?
No. The NOVA1 recloser is not compatible with the
Form 5/TS control. Though very similar, the NOVA1
and NOVA-TS reclosers have different operating
mechanisms. This requires different electrical signals be sent to the respective controls for monitoring
and response purposes.
Just as the NOVA-TS and Form 5/TS control are an
integral unit, so are the NOVA 1 recloser and NOVA1
control. See Bulletin Number 99016 for more information on the NOVA 1 system.

No. The NOVA-TS recloser is not compatible with
the NOVA1 control. Though very similar, the NOVA1
and NOVA-TS reclosers have different operating
mechanisms. This requires different electrical signals be sent to the respective controls for monitoring
and response purposes.
Just as the NOVA-TS and Form 5/TS control are an
integral unit, so are the NOVA 1 recloser and NOVA1
control. See Bulletin Number 99016 for more information on the NOVA 1 system.
34.What are the advantages of the NOVA-TS over
the other competitors?
While there are several new ideas and off e r i n g s
from triple-single manufacturers, Cooper Power
Systems was the first recloser manufacturing company to offer single-phase trip/three-phase lockout
originally with the 3H and 6H reclosers. This commitment to innovation, combined with the efforts of
our Thomas Edison Research Facility along with
Systems Engineerings, Advanced Co ntr ol
Development, and Kyle Switchgear, includes developing algorithms to provide dependable and predictable results in multiple-fault scenarios.
