Electrical Power Quality Monitoring Equipment of Office Buildings for Energy Management
Features:
a.) Number of input channels
Max. 24 channels/device (configurable as voltage or current input)
b.) Measured values:
- instantaneous value of voltage
- instantaneous value of current
c.) Calculated values
- RMS voltage
- RMS current
- Apparent power
- Active power
- Reactive power (incl. capacitive/inductive indication)
- Power factor
d.) Averaging period for calculation: 1 min.
e.) Built-in GSM module for realizing GPRS communication using
different protocols (FTP, http, SNMP) with capability of SMS
sending function, special warnings as required and defined by the
customer
f.) Built-in flash memory to prevent data loss (min. 16MB NOR
flash) with microSD support
g.) Large number of configurable alarm possibilities (power cut,
overcurrent, overvoltage, capacitive/ inductive reactive energy is
over the threshold value, etc.) according to the customer’s needs
h.) Upload periods of calculated values to remote server: 10 min. …
24 hrs. (configurable)
i.) All parameters and the firmware can be updated remotely via the
main wireless communication interface (GPRS/WiFi)
j.) Protection
- Voltage measurement overload (1 min.): 1.5 × Vn
- Voltage isolation: 2kV RMS (1 min., 50Hz)
- Pulse overload capability: 1kV (8/20us)
- Thermal protection
- Housing: IP65
Optional functional:
Saving time domain functions of current and voltage (all measured
instantaneous values are stored) in case of power cut or other
alarm events (min. 0.2s /10 period/, max. 5 sec, according to the
sampling frequency and the number of input channels)
