Section 2(1) in Rajasthan Electricity Regulatory Commission (Metering) Regulations 2007
(1)In these regulations, unless the context otherwise requires;(i)"Apparent Energy" means the integral with respect to time of the Apparent Power.(ii)"Base Computer" (BC) means computer with a provision of a Base Computer Software (BCS) meant to handle the data down loaded from meter(s), to process the data into desired output and to synchronise the time with GPS signal.(iii)"CEA meters Regulations" or "metering Regulation" means the Central Electricity Authority (Installation and Operation of Meters) Regulations 2006.(iv)Central Data Collection System (CDCS) means the computer system located at a central point containing a data base regularly updated from the Settlement In-stations to which it has dedicated communication links.(v)"Common Meter Reading Instruments (CMRI or MRI) or Hand held terminal (HHT)" means a meter reading instrument with necessary accessories capable of interrogating various makes of alternating current (AC) static electrical energy meters when loaded with the corresponding meter specific soft-ware(s) called meter reading instrument program(s).The CMRI shall be capable to extract information about energy data, load survey data, meter status and meter anomaly data from the memory of the meter as stored in preset cyclic order for retrieval at later stage.(vi)"CT-VT or CT-PT Set" means equipment comprising of both Current Transformer and Voltage Transformer.(vii)"Data Concentrator" means a center to club the processed data received from the connected meter(s)/stations for onward transmission through dedicated communication channels to CDCS.(viii)"Demand Period" means the period over which Active Energy, Reactive Energy or Apparent Energy is integrated to produce average Demand Values. For settlement purpose, unless the context requires otherwise, each Demand Period shall be of 15 minutes duration, and shall finish at 24:00 hours.(ix)"Demand Values" in the context off(a)"Demand value energy" means active energy, reactive energy or apparent energy drawn during one demand period commencing at 00.00 hours.(b)"Demand value power" expressed in MW, MVAr or MVA, means four times the value of MWh, MVArh or MVAh recorded during the 15 minutes demand period or two times the value of MWh, MVArh or MVAh recorded during the 30 minutes demand period. The demand values are quarter hour or half hour demands and these are identified by the time of the end at the Demand Period, one of which shall finish at 24:00 hours.(x)"Load Survey" means a database of load values stored in energy meter during predefined time interval. Load survey contains database for different parameters for predefined number of days.(xi)"Maximum Demand [MD]" means the average kVA delivered at Metering point of the consumer, during any demand period of maximum use during the month as specified by the Commission. The Licensee, however reserves the right to shorten this time period, with the approval of the Commission.(xii)"Metering System" means the System which shall comprise of meter (instrument) along with associated equipments and accessories like wiring, meter cabinet/meter box, test terminals blocks etc. required for measurements.(xiii)"NABL" means National Accreditation Board for Testing & Calibration Laboratories.(xiv)"Remote Transmitting Unit (RTU)" means a data transmission unit in digital and sequential mode i.e. to transmit low level analogue/digital signals from transducers, switches, relays etc. connected to it and to transmit received signal to devices connected to it.(xv)"Settlement In-station" means a computer-based system, which collects or receives data on routine basis from selected out-station system linked to CDCS.(xvi)"Supply Code" means RERC (Supply code & connected matters) Regulation 2004.(xvii)"Transducer" means a device to convert high-level parameters (MW, MVA, Amp, and Volt etc.) into low-level transmission signal.
