ACTIVE ELECTRIC ENERGY COUNTERS THREE-PHASE ELECTRONIC SEA3
Three-phase electronic energy meters SEA3 are electrical products that are analogue digital devices that produce summation and indication on the electromechanical readout device of the amount of electricity consumed directly in kilowatt hours.
Part number:
Supplier:
PJSC "SIGNAL"Description
Appointment
Accounting for active electricity by one or two tariffs in three-phase three or four-wire AC circuits directly or through current and voltage measuring transformers, either autonomously or as part of information and measurement systems as an energy increment and power measurement sensor.
Application area
In the domestic and industrial sectors, when electricity is consumed from a three-phase power grid (industrial and commercial enterprises, residential and public buildings, mobile structures, cottages, dachas, garages, etc.).
Normative provision
The meters are designed and serially produced in accordance with the requirements of GOST R 52320 - 2005 (IEC 62052 - 11: 2003), GOST R 52322 - 2005 (IEC 62053 - 21: 2003), technical specifications of IZHSK. 411152.003 TU and safety requirements established by GOST R 51350 - 99. They are included in the State Register of Measuring Instruments of Russia No. 18264-06 and several CIS countries. The meter is certified.
Features
Are executed on the basis of the specialized integrated microcircuit on technology of surface installation.
They have high technological reserves according to the accuracy class.
Resistant to mechanical and climatic influences.
Resistant to failures and short interruptions of supply circuit voltage.
Meet the requirements for electromagnetic compatibility.
Protected from self-propulsion and the effects of external permanent and alternating electromagnetic fields.
They have a pulse telemetric output and a work light indicator in which the functions of indicating the presence of voltage in the network and the load of the consumer are combined.
The two-tariff version has an input for tariff switching.
Reliability Features
The average operating time to failure is 140,000 hours.
The average life of the meter is 30 years.
Warranty period - 18 months.
Calibration interval - 16 years.
Design
Structurally, the meter is made in a plastic housing, providing a degree of protection against the ingress of dust and water IP51. In the case there is a meter block, which consists of a terminal block with three or two measuring current transformers, a printed circuit board with surface and volumetric erection of electronic components and a reading device. The terminals for connecting the meter to the network, the telemetry output and the control circuit for the state of the summing devices are closed by a sealed plastic cover. The counter is sealed with seals from the manufacturer's factory and state verifier.
