Description counter tse2727

Area of ​​use of the electric power meter tse2727These electricity meters are a design that provides instant measurements voltage output signals, with further calculation of active electricity and its calculation at tariffs with respect to specified charging schedules, which are controlled from the set quartz clock report accuracy.

Electricity meters have such basic blocks and units:

  • resistive current separators in voltage circuits;
  • voltage measuring transformers in current circuits;
  • accounting liquid crystal mechanism with a screen on the indicator to register, display and save information about taken into account energy and other indicators;
  • electrical unit with power supply and power converter, which is used to measure the output signals voltage and current, active energy metering, charging of accumulated electricity, displaying data on the screen and output appliances;
  • electronic test input for calibration of the meter tse2727;
  • input pulse device for telemetry data in centralized information collection systems;
  • step-by-step interface for exchanging data with external equipment or an installed module of the modem for exchanging information over the electrical network;
  • diode indicator of the counter, which is triggered along with the test input.

Structurally, tse2727 counters are made in the form of an electrical module, a clip cover, a pressure plate and a housing.

The body is made of casing and base. Fixing the casing to the base and fixing the clamping plate cover implies the possibility of installing seals power company and state adviser. The design of the case has a level of protection IP 51 from moisture and dirt. The current and voltage circuits of electric meters are protected from current and voltage drops.

Taking into account the configuration of the design documentation and the specific requirements of the client, the tse2727 meters have different design options:

  • on base or rated voltage and current;
  • according to the type of connection to the network: for direct connection and using measuring current transformers, or using measuring voltage and current transformers;
  • by the type of installed input interfaces for connecting to a local network of information exchange;
  • according to the number of measuring parts: two- and three-element.

Technical data of the electric power meter tse2727Counters tse2727 create measurement and show current indicator average (over 60 s) total active power, which takes place in 3 phases.

The limit of the possible measurement error of the passing indicator of the average power of 6 m is indicated in the formula:

§M = ± (5d ± 0.02-Pmax / Px), where

  • Рх - determination of the measured power;
  • P max - the definition of the greatest power.

The LCD display of the recorded electricity occurs on 6 decimal places immediately in kW / h, and the current average reading is on 5 decimal places in watts.

Counter functions tse2727

Counter tse2727 creates the following functions:

  • Seasonal change of tariffication schedules with indication of the time of season change;
  • multi-tariff indicator of the use of active electricity with the probability of setting preferential pricing options for holidays, weekends and Saturdays;
  • an indication of the date and time of the exchange of information with external information processing equipment, for example, with a PC.
  • daily fixation of the electricity used at the set time of day;
  • display on the LCD of the energy selected at all tariffs, indicators of the passing date, time, passing approximate active power;
  • fixing a half-hour constant power and taking into account daily schedules of thirty minute power;
  • monthly fixation (at the set date and time) and preservation of recorded indicators recorded electricity for each tariff up to four months;
  • fixing the highest rates, as well as the date and time of exceeding the specified value of thirty minutes of power and the output signal of the excess of a given power;
  • fixing the minima and maxima of the thirty-minute capacity while maintaining the date and time of their determination;
  • fixation of adjustments of the accounting device tse2727;
  • fixing off the electrical network.
