Excitation System Clause Samples

The Excitation System clause defines the requirements and specifications for the equipment and controls that regulate the voltage output of a generator by supplying current to its field windings. In practice, this clause outlines the technical standards, performance criteria, and maintenance obligations for the excitation system, ensuring it operates reliably and integrates with other protective and control systems. Its core function is to ensure stable and safe generator operation by maintaining proper voltage levels, thereby preventing equipment damage and supporting overall system reliability.
Excitation System. (a) A continuous fast acting automatic excitation control system of proven design shall be provided to control each generator’s voltage without hunting or instability over the entire operating range of the generators. (b) The excitation system shall be provided with a fast acting MVAR limiter so as to prevent the generator output falling below safe limits. A power system stabiliser shall be incorporated in the excitation system of each generator. BPDB shall provide the settings for the power system stabiliser. The AVR shall be provided with but not limited to Quadrature Droop Compensation and Cross Current Compounding. Protection features, as part of the system shall include overvoltage, overcurrent, voltage transformer (VT) fuse failure, diode failure, overfluxing, and AVR power supply failure. A field shorting or discharge switch feature shall be included in the system as protection against over stressing the generator insulation in the event of a fault. (c) Manual excitation control facilities shall be provided as back up to the automatic channel, and shall have an adequate range to allow for control of excitation for testing purposes. A true null balance shall be provided to allow for smooth excitation transfer between manual and automatic control.

  • Information Systems The Customer is aware that vehicles manufactured, supplied or marketed by a company within the Volvo Group are equipped with one or more systems which may gather and store information about the vehicle (the “Information Systems”), including but not limited to information relating to vehicle condition and performance and information relating to the operation of the vehicle (together, the “Vehicle Data”). The Customer agrees not to interfere with the operation of the Information System in any way.

  • Distribution System The Transmission Owner’s facilities and equipment used to transmit electricity to ultimate usage points such as homes and industries directly from nearby generators or from interchanges with higher voltage transmission networks which transport bulk power over longer distances. The voltage levels at which Distribution Systems operate differ among areas. Distribution Upgrades – The additions, modifications, and upgrades to the Transmission Owner’s Distribution System at or beyond the Point of Interconnection to facilitate interconnection of the Small Generating Facility and render the transmission service necessary to effect the Interconnection Customer’s wholesale sale of electricity in interstate commerce.

  • DTC DIRECT REGISTRATION SYSTEM AND PROFILE MODIFICATION SYSTEM (a) Notwithstanding the provisions of Section 2.04, the parties acknowledge that the Direct Registration System (“DRS”) and Profile Modification System (“Profile”) shall apply to uncertificated American Depositary Shares upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC pursuant to which the Depositary may register the ownership of uncertificated American Depositary Shares, which ownership shall be evidenced by periodic statements issued by the Depositary to the Owners entitled thereto. Profile is a required feature of DRS which allows a DTC participant, claiming to act on behalf of an Owner of American Depositary Shares, to direct the Depositary to register a transfer of those American Depositary Shares to DTC or its nominee and to deliver those American Depositary Shares to the DTC account of that DTC participant without receipt by the Depositary of prior authorization from the Owner to register such transfer. (b) In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties understand that the Depositary will not verify, determine or otherwise ascertain that the DTC participant which is claiming to be acting on behalf of an Owner in requesting a registration of transfer and delivery as described in subsection (a) has the actual authority to act on behalf of the Owner (notwithstanding any requirements under the Uniform Commercial Code). For the avoidance of doubt, the provisions of Sections 5.03 and 5.08 shall apply to the matters arising from the use of the DRS. The parties agree that the Depositary’s reliance on and compliance with instructions received by the Depositary through the DRS/Profile System and in accordance with this Deposit Agreement shall not constitute negligence or bad faith on the part of the Depositary.
