NOTES


Instruction Book

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 VCP-W circuit breaker. This device is equipped with a set of three bottom terminals. See figure 2.01,2.02 and 2.03. In the upper compartment, the terminals of the G&T device connect to the main bus, and in the lower compartment the terminals of the G&T device connect to switchgear terminals connected to cables. It is important that 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.

WARNING This manual describes a specific

grounding breaker for use at a specific location. It should not be referenced for

any other purpose or installation.

WARNING Use of this device requires that the cell

has been modified from the original factory condition to provide additional

bracing of the ground bus. Use in a stock cell may result in severe

equipment damage and/or personal injury if the ground switch is closed on

an energized 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.


Instruction Book • 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. • 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”. In the E.O. G&T Device design, the K2 lock function is not needed. 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. Figure 2.3.1 Figure 2.3.2 See 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. IB66A5301H11 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” position. Key KD is now removable from lock K4. In this secured Figure 2.3.4 position, the “Closed Locking Device” has blocked operator access Key Lock K4 Interlock 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.
