Features and Measurement 2818 multifunction electricity meter meets the IEC 62053standard for static energy 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 of extreme 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 and apparent 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 optical port. The communication protocol complies with standard. Also data is displayed on 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 metering precision can be digitally verified. 2. High overload-multiplier energy metering (12 times multiplier metering for class 0.5S) by applying variable gain measurement and multi-section digital compensation. 3. Active import and export energy, reactive 4-quadrant energy, and apparent energy 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 units is also programmable as ‘k’, i.e. kWh, kvarh, kVAh. 6. Pulse indication of energy metering using two bright LED’s, which indicate active energy on the left and reactive energy on the right. The duty cycle of LED output is 50%. 4 Channels of pulse outputs are available to other devices. The pulse width is 80 ms. The first channel of pulse output is active import energy, second channel of pulse output is active export energy, third channel of pulse output is reactive energy Q1 and Q2 (first quadrant and second quadrant), fourth channel of pulse output is reactive energy Q3 and Q4 (third quadrant and fourth quadrant). Page 2 国电南自 DSSD/DTSD2818 Multifunction Meter 7. KWh and Kvarh per Phase: meter measures per phase import and export active and reactive energy including: ² Phase A +KWh, -KWh, +kvarh, -kvarh ² Phase B +KWh, -KWh, +kvarh, -kvarh ² 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 fourquadrant 4-tariff demands include total 30 demand data with the occurrence time 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: Rolling interval 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 interval can only be set to 2, 3, or 5 minutes. Demand cycle must be integer multiple of 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 can be 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 total demand may exceed all the demand combined. In other words, the maximum demand is recorded when tariff is being changed. 5. While recording the apparent max demand KVA, meter will record the coincidental active average power KW of demand cycle for user to calculate power factor. 1.3 Instrumentation Data Measurement & Display 1. Phase voltage(ABC) & current(ABCN), power factors(Total, ABC) can be read 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, even when 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 be read through RS485 or optical port.

TOU can be controlled by configuring the parameters that are based on the meter’s internal hardware real-time clock. 2. There are 3 levels of TOU controls, in preferential sequence, they are: “Public Holiday”, “Weekend” and “Season”. 3. There are 4 sets of “daily-profile” tables. Public day, weekend and season can be controlled by selecting one of 4 “daily-profile” tables. 4. TOU for public holidays can set 24 days for every year(format: month day daily profiles or month week daily profiles), and can set 100 days for special day( format: year month day daily-profiles). 5. Weekend TOU can have up to 2 days as weekends for each week. 6. A year can be divided into up to 4 time sections. The shortest section is one day and the longest section one year. 7. “Daily-profile” can divide a day into 10 time sections. Each section can select one of 4 tariffs. The shortest time is one minute, and the longest one day. 1.5 Automatic Data Recording – End of Billing Period 1. Meter can be configured to record dynamic data at a pre-selected time to as billing information including energy storing and demand reset. The time is specified by ‘day/date’ and ‘hour’. 2. The automatic data recording cycle is per month. The date of automatic data recording can be set as non-zero value, namely date XX hour XX. Meterreading date can be chosen from 1 to 28. 3. Automatic data recording can be configured to execute energy recording and demand reset automatically, up to 16 historical energy and demand data can be recorded. 1.6 Load profile recording 1. Meter provides scrolling recording function of load profile data. Data sampling interval is programmable from 1 to 60 minutes. It can be selected to record differential value or accumulative value.

并从零开始启动记录。所以，通常总需量等于某一费率需量，但也会大于所有费率需量 （即最大值发生在费率转换时）。 5 功率因数（可选功能） 视在最大需量发生时，记录当时的需量周期内的平均有功功率，以用来计算功率因 数。 1. 自动抄表的周期为月。自动抄表时间可设置为非“零点”，即 XX 日 XX 时；抄表日只 可在 1-28 日内选择。 3.6 负荷曲线记录功能 1.数据记录采用环形记录方式，可记录的
