In order to test meters, particularly those of the 0.2s class, a testing device with a high degree of accuracy is required. h function. Procedure. Testers will provide the user with very broad information, and should only be used by those that can properly interpret the indications they provide. These two fluxes when cut the disc induce eddy currents in it. SPDCL Meter Testing Service Connection Number *: _____ Mobile Number *: _____ Reason for Complaint *: _____ Meter Testing Details: estimating the energy registration lost during the meter outage for testing. It is mostly used by the power transmission and distribution companies of a country. 1. 2. For the sake of simplicity, the discussion in this section will be mainly based on a single-element (single phase) meter. Smart meter testing ... the lighting combinations that are of interest in this testing procedure. These include the use of different samples for different tests, and simplification of meter specifications in tenders and anti-tamper requirements. All types of relays, including microprocessor relays by secondary injection. In-service/on-site testing is gaining momentum as a part of in-service compliance testing or to carryout metrological testing and functional verifications of meter on receipt of customer’s complaint or internal report. calibration problems of electronic revenue energy meters for direct connection and for connection through current transformers, and it proposes a new calibration procedure which reproduces normal operating conditions better: three-phase configurations of measurement systems, load range during meter testing or shapes of test signals. 4 IS 9000 Basic Environmental testing procedure for electrical and electronic items. 6) The ambient magnetic field strength is lower than 0.5mT. (4) Upgrade Section 7.5 – Work Flow for Metering Data Validation, Estimation and Editing. Enter in the worksheet the pulse output value for the energy reference meters and indicate if the requirements of EL-ENG-12-01 are met. Detailed Analysis of Power and Energy Calibration Errors. Start injection with 25% of rated current with phase shift 30 degrees. BAPL can also calibrate 0.05 class reference energy meters using 0.02 class reference energy meter… It is however assumed that the meter is equipped with a pulsing test LED, LCD, or other pulsing device. Calibration & Testing of Electronic Meters 1. The following testing is done by the Mobile Testing Unit. The meter can be tested in distribution company’s laboratory or any other authorized laboratory (laboratory authorized by state electricity regulatory commission). (1) Before any electricity meters can be manufactured, the authorised manufacturer If there is visible damage, please change the meter. – Meter types (e.g., positive displacement, velocity, electronic) • Flow rates: Water meters will be tested at low , intermediate, and high flow rates relevant to customer usage profile, which is required to determine meter accuracy. The meter test equipment uses digital amplifiers to generate voltages and currents. Standard meter will calculate actual injected Energy. Older dimmers used ... Each stage of the smart meter energy measurement has possible errors due to limits in the hardware. The metering equipment must be appropriate for the load and tariff . Electricity meter testing bench is used to calculate the accuracy of energy meters. I saw a many people around me , who says that their electricity meters are fast/giving over reading. Service fuses at a meter position or FOLCB (overhead supply) 3. State-of-the-art facilities are being established at the lab for testing of smart energy meters. Your primary reason might be related to running costs, building performance, Meters provide the most accurate measurement of voltage, amperage and resistance. BAPL has complete type test facilities for testing energy meters as per Indian and International Standards. General Discussion This document discusses the interpretation and basis for stated measurement accuracy of Ophir Laser Power/Energy meters. GENERAL. Apply 220V A.C to the pressure coil circuit by means of phase shifting transformer. The concept of individual on-site meter testing with current and voltage sources has become increasingly popular. Principle of Operation:The pressure and current coils of shunt and series magnets produce two alternating fluxes, one proportional to voltage and the other proportional to load currents. 15707:2006 covers on-site testing. Power generation. (6) Inclusion of a new Section 9 – Site Specific Loss Adjustment (SSLA). But what happens inside? Meanwhile, various measures are being taken to reduce the duration of meter testing. 6 IS11000 (1984 Fire hazard testing 7 IEC 62052-11 (2003) Electricity Requirements (AC) General Requirements Tests and Test conditions for A.C.Static Watt hour 2. The meter has to be tested within a few months (e.g. 5) The limit of the electricity network phase voltage is 276V. Two- and three-element meters are simply two or three single Electricity metering and monitoring guide 3 Why electricity metering and monitoring matters There may be a variety of reasons for tracking and analysing your energy usage, depending on your situation. Note: If the console is used for testing block interval demand meters only and a control circuit is used for testing demand meters, demand reference meters are not required as per section 6.4.7 of EL-ENG-12-01. Meter. The Department of Energy (DOE) establishes energy-efficiency standards for certain appliances and equipment, and currently covers more than 60 different products. Meter Project, including all technical and functional requirements for smart meters, communication, data concentrators and all software elements, and the project implementation. The connections must be made correctly. 2 months in Maharashtra) and the consumer can request a … The lab is also equipped with a state of art mobile testing unit for testing the equipments at the consumers site. For testing big quantities of meters a robot can also do the job. To ensure the metering is correct, it is essential that the following requirements are met: 1. The primary objective of the meter to register the energy is becoming secondary. Until now, the usual method for testing of energy meters has been to use a stabilized, but not very accurate, power source, in combination with a high-precision reference meter. Procedure for calibration and testing of Single-Phase Energy Meter :-. Inject rated current & voltage to check Energy meter measurements. 4) The electricity network is 3*57.7～3×230V 50/60Hz The maximum current is 10A. 5 IS 12346 (1999) Specification for testing equipment for A.C.Electrical energy meter. (5) Changes made in Section 7.6 Procedural Steps for Validation, Estimation and Editing Process. Energy Meter Testing Procedure, Energy Meter Testing Certificate & Report Of Calibration And Testing Service Service Provider offered by Precision Service Centre from Mumbai, Maharashtra, India A testing procedure for the new, electronic revenue energy meters Abstract: Electric energy meters have been always designed to account energy under sinusoidal conditions and therefore no uncertainty specification was provided outside these conditions. Metering equipment must be fi xed to meter panels in a manner that prevents accidental penetration or abrasion of a conductors insulation. III. 2.2 Installation Sequence 1) Check the meter for any visible damage caused by shipping. Pattern Approval 5. This was considered acceptable when voltage and current distortion levels were low and the old, well known induction meters were used. Standards and Test Procedures. BAPL has been carrying out testing and calibration of energy meters since the last 15 years. Actually you only need to put the meters on the rack. Gas meter stamping, Electricity meter certification, Market surveillance projects for gas and electricity meters, and In-service testing for gas and electricity meters Brexit Check what you need to do Test the testing circuit and voltage indicator. 5 Changes “Philippine Electricity Market Corportion” About PSPCL Punjab State Power Corporation Limited (PSPCL) is the electricity generating company of the Government of Punjab state in India. Results Zero volt reading to be obtained. METER INSPECT PROCEDURE. Apply a load of 2 Amps by switching on the load. Procedure for testing of Energy meter (KSEB) (Refer Supply code:115) (1) The meter shall normally be tested in the laboratory of the licensee, approved by the Commission. R epublic of the P hilippines ENERGY REGULATORY COMMISSION. CALIBRATION AND TESTING OF SINGLE PHASE ENERGY METER.
