Type VCP-W Ground & Test

Device (Simple)

1.0 INTRODUCTION

Type Vac Clad-W switchgear assemblies are designed with all the bus work completely insulated for safety.

Since the current carrying parts are not readily accessible, the type VCP-W Ground & Test Device (G&T

Device) is designed for insertion into the breaker compartment to gain access to the primary stationary

contacts. It provides a convenient means to:

1. Ground the circuit for maintenance work.

2. Apply potential for cable testing.

Note About Roll-On-Floor Option

There is an equivalent style number to have a particular G&TD come with Direct Roll-On-Floor (ROF) wheels

factory installed. The ROF option is only for use with Direct-Roll-In breaker cells.

Please contact your Eaton Sales Office for further information.

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.

2.0 DESCRIPTION

The G&T Device is a drawout element that can be inserted into a

upper or lower circuit breaker compartment in the same manner as a type

VCP-W circuit breaker. This device is equipped with a set of three upper

terminals. See figure 2.0.1, 2.02 and 2.03. In the lower compartment

the terminals of the G&T device connect to the main bus, and in the

upper compartment the terminals of the G&T device connect to the

switchgear terminals connected to cables. It is important the the user

review switchgear compartment configuration to confirm the circuit that

he/she wish to ground prior to using this device.

This device is deeper than the standard VCP-W breaker.

The stored energy closing mechanism for the power grounding

breaker is the same as used in type VCP-W breakers. It is capable

of applying the ground against a “Live” circuit if operational errors

Figure 2.0.1

have not cleared the circuit. However, in such a case, the relaying

G&T Device

at the source of power is expected to cause the source interrupter

to clear the circuit.

2.1 POWER GROUNDING BREAKER OPERATION:

2.1.1 Closing

The power grounding breaker is closed by the remote operating station at the end of a 50 ft. long

cable (supplied with the device) upon depressing the “CLOSE” pushbutton (note that the

pushbutton does not have to be held depressed.):

1. The closing springs start to charge

2. After the springs are fully charged, they automatically

discharge to close the grounding breaker contacts.

Once the grounding breaker is closed, it can be locked in the

“Closed” position by removing the cable from the receptacle on the

device and locking the sliding cover that permits access to the

manual “Push to Open” button. See Figure 2.1.1.1.

Figure 2.1.1.1

Manual “Push to Open” Button Covered

2.1.2 Opening

The grounding breaker can be

opened by manual operation of

the “Push to Open” button

located behind the sliding cover

on the device front panel. See

Figure 2.1.2.1. The grounding

breaker can be opened

electrically using the remote

operating station. See Figure

2.1.2.2. The “OPEN”

pushbutton must be depressed.

Figure 2.1.2.1 Figure 2.1.2.2

For safety reasons, the breaker

Manual “Push to Open” Button Remote Operating Station

is prevented from opening in

less than 20 seconds after closing.

2.2 VCP-W INTERLOCKS AND SAFETY FEATURES

The device is designed to provide as many interlocks and safety features as practical for the

personnel performing any of the operations described earlier.

The device cannot be levered into or out of the “Connected” position unless the grounding breaker is open:

Upon levering a device with a closed grounding breaker into or out of the “Test” position, the

breaker is tripped open by the cam on the floor in the compartment.

In the “Connected” position, engaging the levering crank will trip the grounding breaker open.

An indicator on the front panel shows the status of the grounding breaker contacts, “Open-

Ungrounded” or “Closed-Grounded”. See Appendix A.

The grounding breaker can be locked closed with a padlock. This is accomplished by locking

the sliding cover on the device front panel to prevent access to the manual “Push to Open”

button. See Appendix A.

The grounding breaker cannot be manually closed. The spring charging socket and manual

close button are both covered by the device front panel. See Appendix A.



The grounding breaker can be closed only electrically by a remote operating station at the end

of a 50 ft. cable supplied with the device.

Instruction Book

The power to operate the grounding breaker in this device is obtained through the secondary

disconnect in the breaker 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 breaker is inadvertently

closed on an energized circuit. See Appendix C.

The control switch cable is connected to the device with a twist lock connector.

2.3 INTERLOCKS - BASIC ELEMENTS DESCRIPTION

Key Lock K1 (Keys KU and KB) - The K1 interlock is a two cylinder lock used to electrically

enable or disable the G&T Device.

In the E.O. G&T Device design, the K1 lock is a two cylinder transfer lock with a switch associated

with it. The switch is closed when Key KB is retained. The switch is open and the G&T Device

electrically disabled when Key KU is retained. See Figure 2.3.1.

Key Lock K2 (Keys KB and KC) - The K2 interlock is a two cylinder lock used to mechanically

lock the G&T Device “OPEN”.

It is not possible for an

operator of the G&T Device to

manually charge the closing

springs or to manually close the

device to ground.

See Figure 2.3.2

Figure 2.3.1 Figure 2.3.2

Key Lock K1 Interlock Key Lock K2 Interlock

Key Lock K3 (Key KC) - The K3

interlock is a single cylinder lock,

that when locked, prevents the G&T Device from insertion into the

breaker compartment.

In this design, the K3 lock in the locked position blocks the G&T

Device levering latch from engaging the levering nut in the breaker

compartment, and an interference hook prevents rolling the breaker

in to the cell. In addition, the K3 lock is used to prevent operation of

the levering in screw in the Connected position. Operation in the test

position is prevented by the interference hook; test operation must be

performed out of the cell using the test umbilical cable. Key KC is

Figure 2.3.3

removable with the lock bolt extended and the key normally resides in

Key Lock K3 Interlock

Key Lock K2. See Figure 2.3.3.

Instruction Book

IB131007EN REVISION 2 For more information visit: www.Eaton.com

Key Lock K4 (Keys KB & KD) - The K4 interlock is a two cylinder

lock used to mechanically lock the G&T Device in the ”CLOSED

-Grounded” position.

In this design, the K4 interlock is a two cylinder lock used with the

“Closed Locking Device” to prevent the G&T Device from being

opened. When the G&T Device is in the “OPEN-Ungrounded”

position, the “Closed Locking Device” is disabled. Key KD is

retained when the lock bolt is retracted. When the G&T Device 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”

Figure 2.3.4

position. Key KD is now removable from lock K4. In this secured

Key Lock K4 Interlock

position, the “Closed Locking Device” has blocked operator access

to the manual “OPEN” pushbutton. Also, in this secured position,

an interlock switch electrically disables the electrical “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

padlock. See Figure 2.3.4.

Key Lock K5 (Key KD) - The K5 interlock is a single cylinder lock

used to open and lock the test port shutters.

In this design, the K5 interlock is a single cylinder lock. Key KD is

removable when the lock bolt is extended and the key normally

resides in Key Lock K4. Key KD is available only when the G&T

Device is locked “CLOSED-Grounded”. Key KD is removable from

the K5 interlock in two extended bolt positions. One position is when

the Test Port shutters are closed. The second position is when the

Figure 2.3.5

Test Probes are inserted in the Test Ports and they are being

Key Lock K5 Interlock

retained by the “detent” position of the shutter. See Figure 2.3.5.

Selector Switch - A selector switch has the “OPEN”, “OFF” and

“CLOSE” positions and shall operate in association with the remote

“OPEN”/”CLOSE” pushbutton station. See Figure 2.3.6.

In this design, the selector switch functions as described below. In

the “OFF” position, the G&T Device is electrically disabled. The

selector switch is padlockable in the “OFF” position. This provides

the padlockable function for the Key Locks K1 and K2. The selector

Switch in the “CLOSE” position allows the execution of a remote

“CLOSE” command. The “OPEN” function is disabled. Conversely,

the selector switch in the “OPEN” position allows the execution of a

remote “OPEN” command. The “CLOSE” function is disabled,

assuming all other interlocks would permit the operation.
