Measurement Transformers Clause Samples

The Measurement Transformers clause defines the requirements and standards for devices used to measure electrical quantities such as voltage and current within a system. It typically outlines the specifications for accuracy, installation, maintenance, and calibration of current and voltage transformers that are integral to metering and protection schemes. By establishing clear guidelines for these measurement devices, the clause ensures reliable data collection and system safety, thereby minimizing errors in billing, monitoring, and fault detection.
Measurement Transformers. (A) The terms "current transformer" and "voltage transformer" used in paragraphs 3.3 and 3.4 below do not preclude the use of other measuring techniques with a performance equal to that specified for such Measurement Transformers. (B) For each circuit, current transformers (“CT”) and voltage transformers (“VT”) must meet the requirements set out in paragraphs 3.3 and 3.4 below. (C) Where a combined unit measurement transformer (i.e., VT and CT) is used, the Tests for Accuracy described in clause 8 of IEC Standard 44-3 in relation to mutual influence effects must also be met. (D) All Measurement Transformers must be of a wound construction.

Measurement Transformers. For each circuit, current transformers ("CT") and voltage transformers ("VT") shall comply with the requirements set out in Sections 5.1.1 and 5.1.2. Additionally, where a combined measurement transformer (VT & CT) is provided the "Tests for Accuracy" as covered in clause 8 of IEC Standard 44-3 covering mutual influence effects shall be met.

Measurement Transformers. For all installations with new/replaced measurement transformers the Meter Operator shall confirm and record from site tests and inspections:- 22.2.1 the installed unit details including:- serial numbers, rating, accuracy class, ratio(s); Superseded 22.2.2 CT ratio and polarity for selected tap; and 22.2.3 VT ratio and phasing for each winding. For installations with existing measurement transformers the Meter Operator shall wherever practically possible perform Sections 22.2.1, 22.2.2 and 22.2.3 above, but at a minimum must confirm and record VT and CT ratios. If the Meter Operator is not able to confirm the CT ratio on site then the Meter Operator must record the reason why on the commissioning record and liaise with the relevant Distribution (or Transmission) Business to obtain the required information.

  • Measurement Should the State terminate this contract as herein provided, no fees other than fees due and payable at the time of termination shall thereafter be paid to the Engineer. In determining the value of the work performed by the Engineer prior to termination, the State shall be the sole judge. Compensation for work at termination will be based on a percentage of the work completed at that time. Should the State terminate this contract under paragraph (4) or (5) above, the Engineer shall not incur costs during the thirty-day notice period in excess of the amount incurred during the preceding thirty days.

  • 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. 5.7.2 BellSouth shall make available the following channelization systems and interfaces: 5.7.2.1 DS1 Channelization System: channelizes a DS1 signal into a maximum of twenty- four (24)

  • Mileage Measurement Where required, the mileage measurement for LIS rate elements is determined in the same manner as the mileage measurement for V&H methodology as outlined in NECA Tariff No. 4.

  • Measurement and Billing 5.6.1 For billing purposes, each Party shall pass Calling Party Number (“CPN”) information on each call carried over the Traffic Exchange Trunks at such time as the originating switch is equipped for SS7 and from all switches no later than December 31, 1998. At such time as either Party has the ability, as the Party receiving the traffic, to use such CPN information to classify on an automated basis traffic delivered by the other Party as either Local Traffic or Toll Traffic, such receiving Party shall bill the originating Party the Local Traffic termination rates, Intrastate Exchange Access rates, or Interstate Exchange Access rates applicable to each minute of Traffic for which CPN is passed, as provided in Exhibit A and applicable Tariffs. 5.6.2 If, under the circumstances set forth in subsection 5.6.1, the originating Party does not pass CPN on up to ten percent (10%) of calls, the receiving Party shall bill the originating Party the Local Traffic termination rates, Intrastate Exchange Access rates, Intrastate/Interstate Transit Traffic rates, or Interstate Exchange Access rates applicable to each minute of traffic, as provided in Exhibit A and applicable Tariffs, for which CPN is passed. For the remaining up to ten percent (10%) of calls without CPN information, the receiving Party shall bill the originating Party for such traffic as Local Traffic termination rates, Intrastate Exchange Access rates, Intrastate/Interstate Transit Traffic rates, or Interstate Exchange Access rates applicable to each minute of traffic, as provided in Exhibit A and applicable Tariffs, in direct proportion to the minutes of use of calls passed with CPN information. 5.6.3 If the originating Party does not pass CPN on more than ten percent (10%) of calls, or if the receiving Party lacks the ability to use CPN information to classify on an automated basis traffic delivered by the other Party as either Local Traffic or Toll Traffic, and the originating Party chooses to combine Local and Toll Traffic on the same trunk group, it will supply an auditable Percent Local Use (“PLU”) report quarterly, based on the previous three months’ traffic, and applicable to the following three months. If the originating Party also chooses to combine Interstate and Intrastate Toll Traffic on the same trunk group, it will supply an auditable Percent Interstate Use (“PIU”) report quarterly, based on the previous three months’ terminating traffic, and applicable to the following three months. In lieu of the foregoing PLU and/or PIU reports, the Parties may agree to provide and accept reasonable surrogate measures for an agreed-upon interim period. 5.6.4 Measurement of billing minutes for purposes of determining terminating compensation shall be in conversation seconds.

  • 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 ▇▇▇▇▇▇. At the commencement of each project, the onsite management and employee representatives shall agree which is to be the applicable automatic weather monitoring station.
