1. Features and Measurement

2818 multifunction electricity meter meets the IEC 62053standard for staticenergy meters. The main features of meter include none physical adjustment

components, digital signal processing, digital filters, digital error correction,digital calibration, immunity to temperature fluctuation, and excellent stability.Due to its 12 times overload multiplier, meter can record energy usage ofextreme low load. Its accurate measurements of voltage, current, power factors,and power can replace a series of indicating instruments and transmitters.

The basic functions of meter include measurement and registration of active andapparent bidirectional (import and export) energy, reactive four-quadrant energy,maximum demand indications and other related functions.

Data can be retrieved through energy registering system, which consists of

load-control terminal or other data terminal devices via RS485 bus or IR opticalport. The communication protocol complies with standard. Also data is displayedon LCD in large characters with IEC 62056-61 compliant OBIS codes.

2818 Meter data processing functions include:

1.1 Energy Metering

1. Energy measurement using digital measuring chips, therefore meteringprecision can be digitally verified.

2. High overload-multiplier energy metering (12 times multiplier metering forclass 0.5S) by applying variable gain measurement and multi-section digitalcompensation.

3. Active import and export energy, reactive 4-quadrant energy, and apparentenergy metering through data provided by energy measuring integrated chips.Reverse units will be recorded into sum KWh.

4. 4-Tariffs and total energy metering of active import and export energy,reactive 4-quadrant energy, and apparent energy.

5. Energy displays in 8 digits, decimal points configurable from 0 to 2 digits.

User can select to display Primary values or Secondary values. Energy unitsis also programmable as !k", i.e. kWh, kvarh, kVAh.

6. Pulse indication of energy metering using two bright LED"s, which indicateactive energy on the left and reactive energy on the right. The duty cycle ofLED output is 50%.

4 Channels of pulse outputs are available to other devices. The pulse width is80 ms. The first channel of pulse output is active import energy, secondchannel of pulse output is active export energy, third channel of pulse outputis reactive energy Q1 and Q2 (first quadrant and second quadrant), fourthchannel of pulse output is reactive energy Q3 and Q4 (third quadrant and

fourth quadrant).

7. KWh and Kvarh per Phase: meter measures per phase import and exportactive and reactive energy including:

² Phase A +KWh, -KWh, +kvarh, -kvarh² Phase B +KWh, -KWh, +kvarh, -kvarh² Phase C +KWh, -KWh, +kvarh, -kvarh

All these values can be displayed on LCD or read from communication ports.

1.2 Maximum Demand Indication

1. Calculating functions of active import and export energy, reactive four-quadrant 4-tariff demands include total 30 demand data with the occurrencetime of each demand data. The format of time stamp is #month, date, hour,minute$. The indication range of energy demand (including power) is 0 -99.9999 kW/kvar/kVA

2. Calculating mode can be Block or Rolling. Sliding/Rolling Mode: Rollinginterval can be set to 1, 2, 3, or 5 minutes and demand cycle can be set to 5,10, 15, 30, or 60 minutes. If demand cycle is set to 60 minutes, rolling intervalcan only be set to 2, 3, or 5 minutes. Demand cycle must be integer multipleof rolling interval.

Block Mode: demand cycle can be set to 5, 10, 15, 30, or 60 minutes.

3. Each average power of demand cycle is calculated and recorded, which canbe displayed or read through load profile.

4. Total demand is not affected when time block is changed, but a rolling

interval before the change will be skipped when calculating tariff demand.The recording will start from zero by eliminating the previous rolling interval.In general, total demand equals a certain tariff demand. But sometimes totaldemand may exceed all the demand combined. In other words, the maximumdemand is recorded when tariff is being changed.

5. While recording the apparent max demand KVA, meter will record thecoincidental active average power KW of demand cycle for user to calculatepower factor.

1.3 Instrumentation Data Measurement & Display

1. Phase voltage(ABC) & current(ABCN), power factors(Total, ABC) can beread through RS-485 port or optical port, or displayed directly on LCD.

2. Measurement of harmonics values (optional).

3. Measurement of phase angles. (optional)

NOTES:Display for phase sequence is not supported, but if current and phase are matched,the meter will record the electrical energy and maximum demand correctly, evenwhen the phase rotation/sequence is incorrect..

4. Active instantaneous power kW (ABC total), reactive instantaneous power

kvar (ABC total), and apparent power kVA (ABC total) per second can beread through RS485 or optical port.
