THREE-PHASE ELECTRIC ENERGY METER SEA3.

SEA3 SEA3 SEA3М SEA3М
  • Three-phase electric energy meter SEA3 is an electrotechnical product, analog-digital devise that sums and indicates on electromechanical reading device the quantity of electric energy meter input in kWt/h.
    General purpose
  • Measuring of active electric energy by one or two rates in tree- or four-wire three-phase circuits directly or through measuring current and voltage transformers, autonomously or amounting to information and metering systems as a sensor of energy increment and power measuring.
    Standard provision
  • The meters are developed and go into series production according to the requirements of Quality standard ISO 9001 (GOST R ISO 9001-2001), correspond to technical specifications IZHSK. 411152.003 TU, GOST 30207-94 “Static meters of active energy Watt-hours of alternating current (accuracy class 1-2)”, safety requirements determined by GOST R 51350-99. The meters are included in public register of measurement instrumentation in Russia, reference No18264-04, and several countries of the CIS. The meter is certified. Certificate of conformance No 6526270.
    Features
  • The meters are made on the basis of specialized microcircuit by means of surface mounting technology.
  • The meters have large technological margin on accuracy class.
  • Stable to mechanical and climatic influence.
  • Stable to fails and short breaks of mains supply voltage.
  • The meters correspond to the requirements to products on electromagnetic compatibility.
  • The meters are protected from shunt running and influence of constant and alternating external electromagnetic fields.
  • The meters have impulse telemetering output and indicator lamp that operates as indicator of voltage presence in the circuit as well as indicator of a consumer’s load.
  • Double-rate modification has an input for switching the tariff.
    Reliability characteristics
  • Mean time to failure – 72000 hours.
  • Mean lifetime – 25 years.
  • Warranty lifetime – 18 months.
  • Calibration interval – 6 years.
    Construction
  • The meter is made in a plastic case, protection from dust and water penetration - IP 51. The case comprises a meter block consisting of terminal block with two or three measuring current transformers, printed-circuit board with surface and volumetric mounting of electronic components and reading devise. Terminal block has a sealed lid. Meter case is sealed by the division of technical control of the manufacturing plant and by a state officer.
