C. Power Cell Compartment

1. Main Isolating Switch

a. The main power cell shall have an externally-operated, 3-pole, gang operated, fixed mounted non-load-break isolating switch.

b. The isolating switch shall isolate the power bus compartment from the power cell by means of a positively driven shutter mechanism to prevent accidental contact with line terminals in the power bus compartment.

c. The main power cell door shall have a viewing window through which the operator can verify the isolating switch position.

d. The isolating switch shall only have the ability to interrupt the no-load (magnetizing) current of the control power transformer(s) (CPT) and/or potential transformers (PT) supplied inside the controller power cell.

e. In the open position, the isolating switch and contactor shall provide a means of grounding appropriate medium voltage power cell components, bleeding off hazardous stored energy, thus providing safe operation and maintenance.

b. Optional key interlocks, configured to operate with the operating handle or power cell door, shall be available when interlocking is required with another specified

Pump Station 6 Starter Replacement 26 18 39 -8 device, i.e. main breaker, load-break switch, starter, etc.

3. Power Fuses and Fuse Holders

a. The power cell shall be designed to accept bolt-on or clip-on current limiting power fuses.

b. The medium voltage product shall have fixed power fuse holders that are separately mounted in the power cell, not on the contactor, and are located to allow easy inspection and replacement without any disassembly or removal of other components.

c. The power fuses shall provide visual condition indication by way of a spring-actuated blown fuse indicator.

d. The power fuse size shall be selected based on load data provided on the Drawings.

4. Current Transformers

a. The medium voltage power cell shall include current transformers (CTs) as indicated on Drawings. Selection of specific CTs for protection class, accuracy, window coordinated with power conductors, and minimal saturation risk is the responsibility of the supplier. Transformers shall be of sufficient VA capacity to meet the requirements of all the devices connected to them.

b. Each current transformer shall have the primary rating sized appropriately in relation to the full load current rating of the motor or feeder. The secondary of the current transformers shall have a 5 amp output and accuracy suitable for the type and quantity of protection or metering devices connected to it. All current transformer control wiring shall be terminated on the current transformer with locking-type, fork tongue lugs.
