FREQUENCY MEASUREMENTS Sample Clauses

FREQUENCY MEASUREMENTS. As may be reasonably requested by SPP BA, Interchange Equipment Operators may be requested to supply SPP BA with frequency measurements from locations agreed to by the Parties. Operating ZoneInterchange Equipment Operators so requested shall provide accurate frequency measurements from these location(s) with measurement quality indication. Quality indication shall enable SPP to automatically activate the back-up frequency metering equipment upon detection of failure of the SPP’s primary source.

FREQUENCY MEASUREMENTS. As may be reasonably requested by SPP, SPP BA Participants may be requested to supply SPP with frequency measurements from locations agreed to by the Parties. SPP BA Participants that are designated to provide frequency measurements to SPP shall provide accurate frequency measurements from these location(s) with measurement quality indication. SPP BA Participants shall perform annually, against a common reference, checks and calibrations of its time error and frequency devices used to supply SPP with data used by SPP to perform BA functions (“Actions”). For purposes of this section, “annually” shall mean “within a calendar year, with the calendar year beginning on January 1 and ending on December 31;” however, the period between subsequent annual checks and calibrations under this section shall not exceed fifteen (15) months. Documents verifying such Actions shall be provided to SPP BA as requested by SPP.
FREQUENCY MEASUREMENTS. Operating ZoneInterchange Equipment Operators shall provide accurate frequency measurements with quality indication. Quality indication shall enable SPP to automatically activate the back-up frequency metering equipment upon detection of failure of the SPP’s primary source.
FREQUENCY MEASUREMENTS. The frequency must be measured locally for each Delivery Point unless Virtual Delivery Points. Accuracy of frequency measurements must be better than 10 mHz. The setpoint of frequency is 50,000 Hz and must be aligned with the local controller. The BSP must only install a frequency meter for the Delivery Point with limited energy reservoir that directly delivers the Service. For a Technical Unit used as part of the Energy Management Strategy of a Providing Group which has energy limited reservoirs but is not the Delivery Point with which the Providing Group is delivering the Service the BSP is not obliged to install a frequency meter.
FREQUENCY MEASUREMENTS. The frequency measurements must be local, meaning that a frequency meter must be installed at the site of each Delivery Point. This rule is not aplicable in case of Virtual Delivery Points and Technical Units used as part of the Energy Management Strategy which are not performing the FCR Service. In case of a Virtual Delivery PointsPoint, one frequency meter for all Technical Units part of the Virtual Delivery point suffices. The BSP may decide on where to install the frequency meter of the Virtual Delivery Point. If a BSP provides the FCR Service with several Virtual Delivery Points, a different frequency meter must be usedinstalled for each concerned Virtual Delivery Point for redundancy reasons. The frequency meter has a set point of 50,000 Hz and must be aligned with the local controller. It’san accuracy must be at least 10 mHz. 9 or a maximum precision margin of 100kW
FREQUENCY MEASUREMENTS. As may be reasonably requested by SPP, Interchange Equipment Operators may be requested to supply SPP with frequency measurements from locations agreed to by the Parties. Interchange Equipment Operators that are designated to provide frequency measurements to SPP shall provide accurate frequency measurements from these location(s) with measurement quality indication. Interchange Equipment Operators shall perform annually, against a common reference, checks and calibrations of its time error and frequency devices used to supply SPP with data used by SPP to perform BA functions. Documents verifying such actions shall be provided to SPP BA as requested by SPP. The Interchange Equipment Operator shall adhere to the minimum values for measuring devices as listed below: Device Accuracy Digital Frequency Transducer = 0.001 Hz MW, MVAR, and voltage transducer = 0.25 % of full scale Remote terminal unit = 0.25 % of full scale Potential transformer = 0.30 % of full scale Current transformer = 0.50 % of full scale

  • Usage Measurement Usage measurement for calls shall begin when answer supervision or equivalent Signaling System 7 (SS7) message is received from the terminating office and shall end at the time of call disconnect by the calling or called subscriber, whichever occurs first.

  • Temperature Measurement Temperature will be measured by the nearest automatic Melbourne Bureau of Meteorology Monitoring Station for example (but not limited to): Melbourne, Moorabbin, Dunns Hill, Melbourne Airport, Frankston, and Point Xxxxxx. At the commencement of each project, the onsite management and employee representatives shall agree which is to be the applicable automatic weather monitoring station.

  • Methods of Measurement The methods used to identify the educational strengths and needs of students are set forth in the approved Application.

  • Benchmarks for Measuring Accessibility For the purposes of this Agreement, the accessibility of online content and functionality will be measured according to the W3C’s Web Content Accessibility Guidelines (WCAG) 2.0 Level AA and the Web Accessibility Initiative Accessible Rich Internet Applications Suite (WAI-ARIA) 1.0 for web content, which are incorporated by reference. Adherence to these accessible technology standards is one way to ensure compliance with the College’s underlying legal obligations to ensure that people with disabilities are able to acquire the same information, engage in the same interactions, and enjoy the same benefits and services within the same timeframe as their nondisabled peers, with substantially equivalent ease of use; that they are not excluded from participation in, denied the benefits of, or otherwise subjected to discrimination in any College programs, services, and activities delivered online, as required by Section 504 and the ADA and their implementing regulations; and that they receive effective communication of the College’s programs, services, and activities delivered online.

  • Units of Measurement In all correspondence, in all technical schedules, on all drawings and for all instrument scales, SI units of measurement are to be employed. On drawings where IEC or other units have been used it will be in order if the equivalent SI measurement is suitably marked in addition.

  • Measurements All production shall be accurately measured using standards established by the American Gas Association (AGA) and/or the American Petroleum Institute (API) and all measuring devices shall be tamper proof as nearly as possible. Oil royalties due within the terms of this lease shall be calculated on actual and accurate measurements within API standards unless a different means of measurement, subject to Lessor's approval, is provided.

  • Measuring EPP parameters Every 5 minutes, EPP probes will select one “IP address” of the EPP servers of the TLD being monitored and make an “EPP test”; every time they should alternate between the 3 different types of commands and between the commands inside each category. If an “EPP test” result is undefined/unanswered, the EPP service will be considered as unavailable from that probe until it is time to make a new test.
