Protective Relaying on the Generator Circuit Breaker Sample Clauses

Protective Relaying on the Generator Circuit Breaker. MSEDCL will not assume any responsibility for the protection of Generator’s generator(s) or if any other portion of Generator’s electrical equipment. Generator is fully responsible for protecting their equipment in such manner that faults or other disturbances do not cause damage to Generator’s equipment. The following relaying is required solely for the purpose of minimizing the adverse effects of Generator owned parallel generation on the MSEDCL System during abnormal conditions. Additional relaying may be required by Generator to adequately protect their facilities. Relaying on the generator circuit breaker shall include : A synchronizing relay that automatically synchronizing or supervises the manual synchronizing of a generator with an electric system. Directional power relay that operates on a predetermined value of power flow in a specific direction. A negative sequence relay that operates on a predetermined value of negative sequence current produced by an external fault condition. A voltage restrained over-current relay that will operate on a predetermined value of current and a reduced value of voltage. This relay is usually set below full loan current in order to detect three phase faults whose magnitude is determined by the synchronous reactance of the generator. An over-voltage relay that is designed to operate when a ground conditions occurs somewhere on and leaving a generator exceed a preset value.

  • Unbundled Network Element Combinations 4.1 For purposes of this Section, references to “Currently Combined” Network Elements shall mean that the particular Network Elements requested by NewPhone are in fact already combined by BellSouth in the BellSouth network. References to “

  • Integrated Digital Loop Carriers The feeder portion of some loops may be provide by means of Integrated Digital Loop Carrier (IDLC). IDLC provides a fiber optic cable transmission path that travels directly into BellSouth’s central office local switch. Where BellSouth uses IDLC ,if technically feasible and capacity does exist, BST will provide Al-Call with a Designed DS0 UVL by using alternative provisioning techniques including but not limited to such as “hairpinning” and DAC grooming. Alternative provisioning techniques will be provided at no additional cost to Al-Call . Hairpinning involves providing a DS0 signal from an IDLC-served loop to Al-Call ’s collocation equipment by using a dedicated pathway that traverses BellSouth’s central office switch. BellSouth will provide such DS0 signal to Al-Call by establishing a copper cross connect between the BellSouth switch and Al-Call ’s collocation equipment.

  • Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where InterGlobe has requested an Unbundled Loop and BellSouth uses IDLC systems to provide the local service to the End User and BellSouth has a suitable alternate facility available, BellSouth will make such alternative facilities available to InterGlobe. If a suitable alternative facility is not available, then to the extent it is technically feasible, BellSouth will implement one of the following alternative arrangements for InterGlobe (e.g. hairpinning):

  • Transit Traffic The following rates will apply:

  • Unbundled Digital Loops 2.3.1 BellSouth will offer Unbundled Digital Loops (UDL). UDLs are service specific, will be designed, will be provisioned with test points (where appropriate), and will come standard with OC and a DLR. The various UDLs are intended to support a specific digital transmission scheme or service.

  • Local Switching Interfaces 4.2.13.1 Newcomm shall order ports and associated interfaces compatible with the services it wishes to provide as listed in Exhibit A. BellSouth shall provide the following local switching interfaces:

  • Unbundled Channelization (Multiplexing) 5.7.1 To the extent NewPhone is purchasing DS1 or DS3 or STS-1 Dedicated Transport pursuant to this Agreement, Unbundled Channelization (UC) provides the optional multiplexing capability that will allow a DS1 (1.544 Mbps) or DS3 (44.736 Mbps) or STS-1 (51.84 Mbps) Network Elements to be multiplexed or channelized at a BellSouth central office. Channelization can be accomplished through the use of a multiplexer or a digital cross-connect system at the discretion of BellSouth. Once UC has been installed, NewPhone may request channel activation on a channelized facility and BellSouth shall connect the requested facilities via COCIs. The COCI must be compatible with the lower capacity facility and ordered with the lower capacity facility. This service is available as defined in NECA 4.

  • Wire Unbundled DS1 Digital Loop This is a designed 4-wire Loop that is provisioned according to industry standards for DS1 or Primary Rate ISDN services and will come standard with a test point, OC, and a DLR. A DS1 Loop may be provisioned over a variety of loop transmission technologies including copper, HDSL-based technology or fiber optic transport systems. It will include a 4-Wire DS1 Network Interface at the End User’s location.

  • Local Circuit Switching Capability, including Tandem Switching Capability 4.2.1 Local circuit switching capability is defined as: (A) line-side facilities, which include, but are not limited to, the connection between a loop termination at a main distribution frame and a switch line card; (B) trunk-side facilities, which include, but are not limited to, the connection between trunk termination at a trunk-side cross-connect panel and a switch trunk card; (C) switching provided by remote switching modules; and (D) all features, functions, and capabilities of the switch, which include, but are not limited to: (1) the basic switching function of connecting lines to lines, line to trunks, trunks to lines, and trunks to trunks, as well as the same basic capabilities made available to BellSouth’s customers, such as a telephone number, white page listings, and dial tone; and (2) all other features that the switch is capable of providing, including but not limited to customer calling, customer local area signaling service features, and Centrex, as well as any technically feasible customized routing functions provided by the switch. Any features that are not currently available but are technically feasible through the switch can be requested through the BFR/NBR process.

  • wire Unbundled ISDN Digital Loops These will be provisioned according to industry standards for 2-Wire Basic Rate ISDN services and will come standard with a test point, OC, and a DLR. NewPhone will be responsible for providing BellSouth with a Service Profile Identifier (SPID) associated with a particular ISDN-capable Loop and customer. With the SPID, BellSouth will be able to adequately test the circuit and ensure that it properly supports ISDN service.
