CAUTION
BECAUSE OF THE UNIQUE APPLICATION AND VAST VARIETY OF SYSTEM/
USER REQUIREMENTS, SPECIFIC SAFE OPERATING PROCEDURES FOR THE
USE OF THIS DEVICE MUST BE DEVELOPED BY THE USER.
1. Introduction
38 kV Type VCPW-HD Simple Electrical Ground & Test Device
(SEG&TD) assemblies are designed with all the bus work completely
insulated for safety.
Since the current carrying parts are not readily accessible, the type
38 kV SEG&TD is designed for insertion into the switchgear com-
partment to gain access to the primary stationary contacts. It pro-
vides a convenient means to:
•
Ground the circuit for maintenance work and
•
Apply potential for cable testing.
2. Description
The 38 kV SEG&TD (see Figure 1) is a draw-out element that can be
inserted into a switchgear compartment in the same manner as a
VCPW-HD circuit breaker. This device is equipped with a set of three
upper terminals (stabs) (see Figure 2).

SEG&TD operation configuration). Follow steps 2.1 - 3.4
Figure 3. 38 kV SEG&TD (rear view – Test probes & testing
feeder configuration). Follow steps 3.5 – 3.9
This device has longer depth than the standard VCPW-HD breaker.
The stored energy closing mechanism for the power grounding
breaker is the same as used in type VCPW-HD breakers. It is
capable of applying the ground against a “Live” circuit if operational
errors have not cleared the circuit. However, in such a case, the
relaying at the source of power is expected to cause the source
interrupter to clear the circuit.

2.2 38 kV SEG&TD interlocks and safety features
The 38 kV SEG&TD is designed to provide as many interlocks and
safety features as practical for the personnel performing any of the
operations described herein.
The device cannot be levered into or out of the “Connected” posi-
tion unless the grounding 38kV SEG&TD is “Open”.
•
An indicator on the front panel shows the status of the
grounding 38kV SEG&TD contacts, “Open- Ungrounded” or
“Closed-Grounded”.
•
The power to operate the grounding 38kV SEG&TD in this
device is obtained through the secondary disconnect in the
switchgear compartment.
•
The grounding breaker cannot be opened electrically in less
than 20 seconds after closing. This feature permits the source
interrupter to clear a fault if the grounding 38kV SEG&TD is
inadvertently closed on an energized circuit.
•
The control switch cable is connected to the device with a
twist lock connector.
WARNING
IMPROPER USE CAN RESULT IN DEATH, SERIOUS PERSONAL INJURY, OR
PROPERTY DAMAGE.
2.3 Interlocks - basic elements description
There are five interlocks located on the front of the 38 kV SEG&TD.
They are labeled as Lock #1 through Lock #5. The labels also identify
the key(s) to be used in the locks as KB, KC, KD, and KU. Locks #1,
#2, and #4 are two cylinder locks while locks #3 and #5 are single
cylin¬der locks (see Figure 8 and Table 1 for details).

Lock #4 2 KB KD
Lock #5 1 KD -
There is also a mechanical lift lock that, when locked, prevents the
operation of the “Push to Open” and “Push to Close” buttons.
2.3.1 Single cylinder locks
Single cylinder locks are used in two positions on the 38 kV
SEG&TD: Locks #3 and #5. Single cylinder locks have two positions:
locked (see Figure 10) or unlocked (see Figure 9).
Figure 9. Typical single cylinder lock (38 kV SEG&TD Lock #5
shown).
In a single cylinder lock, when the key is inserted into the lock and
turned to the “locked” position, the associated 38 kV SEG&TD func-
tion will be inoperable and the key can be removed. When the key
is in the lock and turned to the “unlocked” position, the associated
38 kV SEG&TD function will be operable and the key is captive in
the lock.
Figure 10. Typical single cylinder lock in the “Locked” position
with the key ready for removal.
2.3.2 Two cylinder locks
Two cylinder locks are used in three positions on the 38 kV SEG&TD:
Locks #1, #2, and #4. Two cylinder locks have four positions (two for
each key): key 1 locked (see Figure 11) or unlocked and key 2 locked
or unlocked (see Figure 12).

In a two cylinder lock, one key must be inserted and turned to
the “locked” position to enable the other key to be turned to the
“unlocked“ position. The key that is in the “locked” position can be
removed from the lock as shown in (Figure 12). When one cylinder is
in the “Locked” position with the key removed, the key in the
second cylinder cannot be turned or removed from the cylinder.
Figure 12. Typical two cylinder lock with one key in the
“Locked” position and one key in the “Unlocked” position with
the key ready for removal (38 kV SEG&TD Lock #4 shown).
2.3.3 Mechanical lift lock
The mechanical lift lock prevents the operation of the “Push to
Open” and “Push to Close” buttons. To activate the lift lock, slide the
left lock plate up until the hole in the plate aligns with the hole in the
right lock plate as shown in (Figure 13). Install a customer-supplied
pad lock through the holes in the left and right lock plates to lock the
plates together.

2.4.2 Lock #2 (keys KB and KC)
The Lock #2 interlock is a two cylinder lock used to mechanically lock
the 38 kV SEG&TD in the “Open” position. The device is locked in
the “Open” position when key KB is in the “Unlocked” position and
key KC has been rotated to the “Locked” position and removed from
the lock (see Figure 16).
Figure 16. Lock #2 locks the SEG&TD in the “Open” position
with key KB retained.
2.4.3 Lock #3 (key KC)
The Lock #3 interlock is a single cylinder lock that, when locked, pre-
vents the 38 kV SEG&TD from insertion into, or removal from, the
switchgear compartment.
In this design, the Lock #3 in the locked position (lock pin extended)
blocks the 38 kV SEG&TD slide handles from being moved to allow
insertion into or removal from the SEG&TD (see Figure 17). Key KC
is removable from Lock #3 when the lock bolt is extended.
Figure 17. Lock #3 with the locking pin extended and the slide
handles locked in position.
ote:N Key KC normally resides in Lock #2 when not being used in Lock #3.
2.4.4 Lock #4 (keys KB and KD)
The Lock #4 interlock is a two cylinder lock used to mechanically lock
the 38 kV SEG&TD in the ”Closed-Grounded” position.
In this design, the Lock #4 interlock is a two cylinder lock used with
the “Closed Locking Device” to prevent the 38 kV SEG&TD from
being opened. When the SEG&TD is in the “Open-Ungrounded”
position, the “Closed Locking Device” is disabled. Key KD is
retained when the lock pin is retracted. When the SEG&TD is
“Closed-Grounded”, the “Closed Locking Device” is free to move
to the right. The lock bolt can now be extended and the “Closed
Locking Device” will be held in the secured “Closed-Grounded” posi-
tion. Key KD is now removable from Lock #4 (see Figure 18).
Figure 18. Lock #4 locks the SEG&TD in the “Closed-Grounded”
position with key KB retained.
In this secured position, the “Closed Locking Device” has blocked
the ability to depress the red manual “Push to Open” button (refer-
ence location Figure 22). Also, in this secured position, the Selector
switch electrically disables the Remote Operating Control “Open”
function; and a mechanical interlock holds the main contacts in the
closed position even if the mechanism is tripped. A padlock hasp
is provided for securing the “CLOSED-Grounded” position with a
customer-supplied padlock for purpose of “Lockout Tag Out” (see
Figure 19).

2.4.5 Lock #5 (key KD)
The Lock #5 interlock is a single cylinder lock used to open and lock
the test port shutters. When rotated, key KD moves the lock pin into
the locked and unlocked positions. Key KD is normally in Lock #4
and is available for use in Lock #5 only when the 38 kV SEG&TD is
locked “Closed-Grounded”.
Key KD is removable from Lock #5 in two extended bolt positions.
One position is when the Test Port shutters are closed (see Figure
20). The second position is when the Test Probes are inserted in the
Test Ports and they are being retained by the “detent” position of
the shutter (see Figures 21 & 49).

tion for DISCONNECT and TEST position.
6. Once fully inserted into the breaker cell (Test Position Slot –
Figure 34), release the slide handles and rotate key “KC” to the
“Locked” position. This will extend the locking pin for Lock #3
to lock the slide handles and the SEG&TD within the breaker
cell. At this point, key “KC” remains in Lock #3 until the 38kV
SEG&TD “Racking” operation is complete.
ote:N When inserting the 38 kV SEG&TD there are two available positions
(shown in Figure 34): “Disconnect” or “Test”. If in the “Disconnect” posi-
tion as shown in (Figure 35), the 38kV SEG&TD cannot be racked in. Follow
instructions in the description under (Figures 35) and reference (Figure 34)
showing the “TEST” position slot that will permit the 38kV SEG&TD to be
racked in.

• Remove Nylon insulator along with the conductor gasket on the
pole units.
• Install the grounding shunt assembly.
3.6 Test probes and testing the feeders
3.6.1 Preparing the test probes and cables.
The test probes should be connected via supplied cables with the
probes using the procedure that follows:
1. Each test probe (692C899H02 – supplied with 38kV SEG&TD)
has a 33 inch long cable that permits the cable ends extend out
past the cell front door. (Figure 43, shows 33 inch long cable).
Additional cable length connection can be made to each probe
assembly supplied, if needed. To extend; strip not more than (1
inch) from the end of each test probe cable. Then splice desired
cable extension length required by customer.
2. A wire lug (wire gage size: 1/0) can be used to connect to the
end of the extension cable by stripping not more than (1 inch)
and further voltage probing/sensing apparatus.
Figure 43. Entire test probe (692C899).
3. Additional (boot or appropriate insulating material) to securely
cover the above option instructions (extension -1 and or lug -2),
must be used to pass the dielectric test.
ote:N Customer to use appropriate Insulation for application voltage.
