Descpription

Supply erection testing and commissioning of • A portable, universal type, light-weight, electronic, precision portable energy meter testing equipment which shall be capable of testing of all types of LT single phase 2 wire, 3 phase 3 wire /4 wire & HT 3 Phase 3 wire/4 wire, whole current and CT operated energy meters in the range of 1 mA to 12 Amps in direct mode & via split core transformers (current circuits) in the range of 200 to 300 Amps at lab as well as at site. Reference Sub Standard meter (ERSS) with complete accessories of accuracy class 0.05 for measuring in the range of 10 mA to 12 Amps in direct mode and of accuracy class 0.2 via split core transformers (current circuits) in the range of 1A to 300 Amps and 500mA to 120A at site as well as in Laboratory both for active and reactive energy. 2. Scope: • A portable, • The ERSS must have micro-processor unit with software support suitable for on line testing of all types of energy meters described in clause 2.1 above at site having memory and capability of communication with the base computer. Computer software should be such that final data be converted for further processing to generate inputs & reports. • The scope of the ERSS meter is not limited to following type of meters but it should be capable of: • Testing electronic meters/electro mechanical energy meters of any latest version including but not limited to the following types: • Ferraris (Induction) Meters with rotating disc. • Static Meters with flashing pulse output of LCD/LED. • Single Phase Active, Apparent and Reactive energy Meters. • Three Phase Active, Apparent and Reactive energy Meters. • Performing the following functions: • Verification of meter circuit connections using vectorial displays and instantaneous parameters. • Harmonic Analysis up to 40th harmonic i.e. the harmonic along with angle for each frequency and time domain with % distortion of each frequency and Total % THD. The ERSS meters quoted and supplied shall be complete with all parts and accessorieswhich are useful and necessary for its efficient electrical and mechanical safe operation and as such parts are deemed to be within the scope of the supply whether specifically mentioned or
