The former is for bi-direction energy measurement, import and export active energy, lagging/leading reactive, four-quadrant reactive energy, and the later is for single-direction energy measurement, import active and leading/lagging reactive energy. Every item above in the two configurations can be metered on time-of-use by a maximum of five tariff rates, i.e. tariff #1, tariff #2, tariff #3, tariff #4, tariff #5. “Season” is defined to a Year, and “switch-time (time period)” to a Day, and “switch time table” to a Switch-Time Combination. A switch-time is corresponding to a tariff. In general, there are 14 seasons in a year, 10 switch-times in a day, and 8 sets of switch-time table. 2.2 Maximum Demand Maximum Demand The TH type energy meter can calculate the maximum demand on import/export active, leading/lagging reactive and occurrence time; while the TF type energy meter on import active, leading/lagging reactive and occurrence time. Both meters can measure the M.D. and occurrence time for five tariffs. The integration period and the sliding time are programmable with a default value of 5-minute HUNAN WEISHENG ELECTRONICS COMPANY LIMITED period and 1-minute sliding. 2.3 Statistics for Energy Quantity per Month Statistics for Energy Quantity per Month The meter is of the capacity of measuring and storing total and TOU energy quantities mentioned-above for current month, last month, last 2 nd month and last 3rd month. Therein, “month” refers to billing period with a programmable starting and ending date and time. 2.4 Function of Measurement Function of Measurement The meter can measure current, voltage, active power, reactive power, power factor in total and respective phase (phase A, B, C), and frequency of power network, and will indicate the direction of power. The accuracy of frequency is 0.01HZ, and class 1.0 for current, voltage, active power, and reactive power. 2.5 Monitoring Function Monitoring Function Phase Fail Record:Phase Fail Record: Phase Fail in a phase will be defined while the phase voltage is lower than 75%Un2% and the corresponding phase current is higher than 5%Ib. The occurrence time of phase fail will be accumulated into the relevant register for this phase. Full Phase Fail Record (optional):Full Phase Fail Record (optional): Full Phase Fail will be defined while the power is off and the current in some phase is higher than 5%Ib. The occurrence time of full phase fail will be accumulated into the relevant register for this phase. Current Loss Record:Current Loss Record: Current Loss in a phase will be defined while the phase current is lower than 2%Ib. The occurrence time of current loss will be accumulated into the relevant register for this phase. Current Unbalance Record:Current Unbalance Record: When the current unbalances happen to three phases and the unbalance ratio is higher than the pre-set limit, the energy meter will accumulate the over- limit hours into the relevant register. Events Record:Events Record: In order to conveniently check the condition of energy consumption, the meter will record various events with occurrence time and status for over voltage, under voltage, voltage loss, current loss, unbalanced current over-limit, reset, demand reset, parameter setting, initial-value setting, power off, power on, and so on. The condition of over voltage is defined for the voltage exceeding 125%Un. Voltage Quality Record (optional):Voltage Quality Record (optional): Based on the preset upper- limit and low-limit of the voltage exam range and that of the voltage quality range, the energy meter will compare the one-minute average voltage with the preset values phase by phase, and then record the time for operation, over upper- limit, and below low-limit. Load Control (optional)Load Control (optional): Based on the preset active power limit, the energy meter compares the one-minute average power with the limit. When the former is bigger than the latter, the device will send out an alarming signal; when the lasting time of such event is longer than the tripping delay time, the device will send out a tripping signal. After the lasting time of power lower than the limit has reached the closing delay time, the tripping signal will release. Prepayment Function (optional): Prepayment Function (optional): Based on the pre eset tariff and alarm limit of surplus electricity fee, the energy meter will calculate the surplus electricity fee. When the surplus electricity fee is less than the alarm limit, the meter will send out an alarm signal and display short-payment; when the surplus electricity fee is null, the energy meter will send out a trip signal. The purchase function can be finished with the international standard IC card. 2.6 Impulse Output Interface and Communication Interface Impulse Output Interface and Communication Interface There are two red LED and infrared indicated lamp on the meter surface for indicating the output of active and reactive power impulse, which are both programmable of the constants and width of the output impulse. The normal settings are: the impulse width is 80ms; for the meter of 31.5(6)A，3220/380V, the impulse constants are 2000imp/kWh、2000imp/kvarh; for the meter of 31.5(6)A，3100V（ or 3 57.7/100V ） , the impulse constants are 5000imp/kWh 、 5000imp/kvarh. The optic-electronic head can be used for error calibration. The 4-way optic-couple dead-contact impulse output is from the auxiliary terminals of the meter for import/ export active, leading/ lagging reactive power, and for the connection with remote terminal unit. The meter is provided with the standard RS485 interface and the infrared data communication interface with the standard protocol of data communication, which is expanded with the data USER MANUAL FOR ELECTRONIC MULTIFUNCTION POLYPHASE kWh METER MODEL DTSD341DSSD3313 reading for load profile and the event recording.
