Measuring and tariff registration of active and reactive energy and power in two directions. Registration of losses.
Accuracy class А/R: 0,5S /1,0
Nom. voltage: 57,7 V; 230 V
Mom.(max.) current: 5(7,5)
А Meter registers three-phase network values (phase currents, voltages, power, etc.),stores load profile and losses profile, keeps events journal, controls load. Great choice of interfaces for application in different AMR. Interfaces: CAN or RS-485, IrDA.
Meters are designed for registration of active and reactive energy and power in one or two directions in three-phase 3- or 4-wire networks of alternating current with frequency 50 Hz through measuring transformers or directly with possibility of tariff registration and transmission of accumulated data about energy consumption through digital interface channels. Operated either autonomous or within any information-measuring systems of technical and commercial registration “INCOTEX PLC”.
Measurement, registration, storage, output to LCD monitor and transmission through interfaces IrDA, CAN, RS-485 of the following data: quantity of registered active and reactive energy separately by each tariff and total of all tariffs:
total from indications reset
for current day and for the beginning of a day
for previous day and for the beginning of a day
for current month and for beginning of a month
for each of 11 previous months and for the beginning of month
for current year and for beginning of a year
for previous year and for beginning of a year
Possibility of registration by 4 tariffs in 16 timing zones of a day separately for each day of a week and holidays. Each month of a year is programmed with individual timetable. Minimum tariff working interval within a day – 1 minute
Possibility of straight direction active energy registration separately in each network phase by each tariff with growing total and by tariffs total with data transmission through wire interfaces.
Technical losses registration in power lines and transformers, forming losses profile;
Measuring, output to LCD indicator and transmission through wire interfaces of the following network values:
instantaneous values of active, reactive and full power by each phase and by phases total with indication full power vector direction
functioning values of phase currents, voltages, angles between network frequency phase voltages o network frequency
power factors by each phase and by phases total
Storage of four-channel archive of average power values of active and reactive energy of two directions and technical losses power profile with voluntary integration time from 1 to 54 minutes. With 30-minutes duration of integration the archives overflow time is 85 days.
Registration of morning and evening maximums of active and reactive power in given interval with monthly timetable
Input of active power and energy limits and programmable control of external consumer switch off load devices in case limits are exceeded.
Transmission of measuring and registration results through interfaces CAN, RS-485, IrDA
Meters programming in the mode of phases summation “on module” to prevent energy theft if meter
Current circuits connection phasing is wrong.
Connection of external backup power supply for reading or measuring values in case of meter power supply failure
Meter journals (circle, 10 records for each event) register:
meter on/off time
phases 1,2,3 on/off time
time of phase voltage exceeding/returning back from permitted limits
devices opening/closing time;
last programming time
tariff timetable correction time
time of exceeding set energy and power limits
total over 15 different events (journal contains 100 records)
accuracy class 0.5s, 1.0s
interfaces: CAN, RS-485, IrDA
network values measuring : P, U, I, cos φ;
four standard galvanic unbound telemetric outputs (DIN 43864), one for each energy type and registration direction;
meters operate towards values increase in case of any wrong phasing of current circuits
load control through external circuits of commutation
self diagnostic with indication of mistakes
presence of journals: events, energy quality values, status
possibility of power backup connection Ubac = 5,5…9 V
Meters indicate on LCD display:
Consumed active and reactive energy value for each tariff (up to four) and total for all tariffs with growing total and accuracy up to hundredth parts of kWh and kVAh;
Phase voltage and current in each phase;
Measured value of active, reactive and full power (integration time 1 s) both for each phase and total for three phases with indication of quadrant, in which there is a full power vector;
Power factor for each phase and total for three phases;
