PRODUCT FUNCTION

●Real time electrical parameter measurement
Real time measurement of three-phase voltage, phase separation current of each circuit, zero sequence current of each circuit, phase separation and total active power of each circuit, phase separation and total reactive power of each circuit, phase separation and total power factor of each circuit, and frequency.
●Real time energy metering
Real time measurement of total active energy in the forward direction, total active energy in the reverse direction, total reactive energy in the forward direction, and total reactive energy in the reverse direction for each of the four circuits; Phase separated active energy and phase separated reactive energy;
●call the police
A total of 10 alarms were detected, including power outage alarm, oil engine power supply alarm, A/B/C three-phase voltage limit exceeding alarm (too low, too high, too high, phase loss), frequency limit exceeding alarm (too low, too high), lightning arrester fault alarm, lightning arrester air disconnection alarm, phase sequence error, and smart meter fault alarm. Among them, voltage phase loss refers to a situation in a three-phase power supply system where the voltage of a certain phase is lower than 60% of the lower limit of the reference voltage. This product has a voltage of 132V, and the load current is less than the starting current.
When a new alarm is generated, there will be flashing prompts and LED prompts for the alarm item on the LCD display. Press any key to display the first alarm item, press the "" or "" key to display the next alarm item, press the "ESC" key to return to the normal data display interface, or automatically switch to the loop display interface after a certain period of time (default 30 seconds).
Alarm data can also be queried locally, as shown in the button display interface in Table 5.4. For example, first press the "ESC" key. When the word "Addr 1" appears, press the "ENT" key, then press the "" or "" key. When the word "Err" appears, press the "ENT" key to enter the alarm options interface. You can use the "" or "" key to query the local alarms. The specific alarm meanings are detailed in Table 5.4.
●Corresponding relationship between alarm items and terminals
Alarm item terminal type terminal number abnormality
City power outage alarm Err 1-E0 wet nodes 5,6 have no power
Oil engine power supply alarm Err 2-E1 7,8 has power
SPD air disconnect alarm Err 8-05 9,10 no power
SPD fault alarm Err 7-E2 dry node 20,21 disconnected
●Switch quantity detection
A total of 7 switch signals were tested, and 3 live line tests were conducted to detect the presence of electricity in the mains, the presence of electricity in the oil engine, and the disconnection of the lightning arrester; The 4-way dry node detection corresponds to the first dry node, the status of the mains circuit breaker, the status of the oil engine circuit breaker, and the fault detection of the lightning arrester.
●Daily data storage and reading for meter reading
Supports up to 256 meter reading day data storage and reading, and can set the meter reading day time point. Store the total active energy, total active power, and A/B/C three-phase current of each circuit.
●Timed freezing storage and reading
The maximum storage has been frozen the last 5120 times, with a default freezing interval of 15 minutes. Store the total active energy, total active power, and A/B/C three-phase current of each circuit.
●Daily frozen data storage and retrieval
The maximum storage capacity has been frozen for the past 1024 days, and the default freezing time is midnight every day; It can freeze the total active energy, total active power, and A/B/C three-phase current of each circuit.
●Alarm storage
Maximum storage of the latest 512 alarm data, using real-time alarm storage.
●Monthly frozen energy storage and reading
Freeze 24 months of electricity data.
●rs485 communication
Two wire RS485 interface, baud rates can be set to 1200, 2400, 4800, 9600, 19200, verification methods can be set to n 8 1, o 8 1, e 8 1, n 8 2, supporting YD/T1363 protocol.
