Capacitor Banks Clause Samples
Capacitor Banks. All materials to be provided by the Owner. The Contractor shall completely assembly on foundation. Note that the foundation and grounding are separate PayCUs, • Transformers - Contractor to assemble Owner procured power transformer after it is delivered to site. Oil to be supplied by the Owner, but effort to fill transformer with oil to be provided by the Contractor. Note that these are strictly the mechanical efforts. Foundation, grounding, wiring, primary connections, etc. will all be handled by separate PayCUs, • Circuit Breakers - Contractor to assemble breakers and mount on foundations. Note that these are strictly the mechanical efforts. Foundation, grounding, wiring, primary connections, etc. will all be handled by separate PayCUs, • Switches - Contractor to assemble switches and mount to the steel structure. These PayCUs assume delivery of a mechanically complete/functional switch. The tasks under the PayCUs shall include all required adjustments, setting of stops, verifications of proper engagement of each set of contacts, final piercing of all pipes and linkages etc. Note that these are strictly the mechanical efforts. Foundation, grounding, wiring, primary connections, etc. will all be handled by separate PayCUs, • Battery - Contractor to mechanically install battery and charger. For both rack and cabinet system batteries shall be individually installed and secured, with battery connections and sensor connections assembled by the Contractor. These materials will be owner supplied. In addition, the Contractor shall ground the battery system to the control house ground using Owner supplied wire. The Contractor shall supply required grounding connectors in the PayCU pricing. External AC/DC connections (back to AC/DC system), cable pulls, terminations, etc. will be handled by separate PayCUs, • Control House Electrical Devices - Individual PayCUs for mounting electrical devices assumes the mechanical effort of mounting the equipment, dressing it out as required, and any miscellaneous hardware required to do so are included. In addition, the Contractor shall ground these devices to the control house ground using Owner supplied wire. The Contractor shall supply the required grounding connectors in the PayCU pricing. In addition, for basic electrical devices the Contractor shall supply electrical boxes for switches, outlets, smoke detectors, etc. in the PayCU price. Separate PayCUs shall be used for pricing Unistrut installs, EMT conduit installations,...
Capacitor Banks. Voltage: 15 kV and 69 kV Purpose: Five 15 kV 5 MVAR capacitor banks inside the system distribution substations (Red Hills, Snow Canyon, Hillside, East ridge and Upper Skyline) and installation of three 69 kV 5 MVAR capacitor banks inside the 69 KV Substations (River and Skyline).
Capacitor Banks. The user shall be able to control capacitor devices. The procedure for controlling these devices shall be the same as that of a switching device except that any supervisory control action must be inhibited for a programmer-adjustable time period after the capacitor/ reactor device has been operated. A message shall appear if an attempt is made to operate the device prior to expiration of that time period & dispatcher is required to give command after expiration of inhibited time period. Tap Changing Transformers: SCADA system shall have the capability to raise and lower the on-load tap position of the transformers from SCADA control centre through supervisory commands. Depending on system conditions, the user may raise or lower the tap positions of On Load Tap Changing (OLTC) transformers. OLTC's tap position needs to be monitored if supervisory control action is to be exercised. OLTC tap position input shall be acquired as an analog value. Tap excursions beyond user-specified high and low limits shall cause the master station to generate an alarm. Supervisory control of OLTCs shall only be permitted when the transformer's control mode is Supervisory. All attempted invalid control actions shall be rejected. For supervisory operations, the initial selection and control of the transformer for a raise/lower operation shall follow the (SCBO) Sequence. Upon receipt of the raise/lower command, the RTU will immediately execute the control action. It shall not be necessary for the user to re-select the transformer for additional raise/lower operations; the user shall only have to repeat the desired number of raise/lower commands, which shall be executed immediately. Normal scanning functions shall not be suspended between the times that repeated raise/lower commands are issued. The user shall be able to cancel the operation or have it automatically cancelled by the master station after a programmer-adjustable time period elapses after the last raise/lower command. This multi- step procedure as described below The RAISE and LOWER pushbuttons shall be displayed. The command shall be launched as soon as RAISE or LOWER is selected. The Raise and Lower buttons shall not be replaced by a single Execute button. The RAISE/LOWER pushbuttons shall continue to be displayed, and it shall be possible to initiate these controls repeatedly without reselection of the controlled point, provided that the execution of the previous control command has successfully been completed.
