Đồng hồ đo và phân tích công suất điện BMR PLA44, PLA34RG,
A power quality analyser designed according the norm EN 61000-4-30 class S with three voltage and four current inputs for measurement of electrical parameters in LV and MV systems. PLA34RG is built on a 32 bit RISC processor that provides sufficient processing capabilities for real-time measurement and calculation of all parameters and values. Continuous sampling of the voltage and current inputs at 40 kHz guarantees the highest accuracy. The PLA34RG is an instrument for power quality monitoring according to the norm EN 50160. It can be used on the energy supplier side as well as on the consumer side in order to find and analyse the root cause of network problems.
Rogowski coil current input
PLA34RG is the variant of PLA34 with inputs for Rogowski coils. Digital integrator for current range change is integrated inside the instrument PLA34RG. Internal digital integraters offers the following measuring current ranges 10 A, 30 A, 100 A, 300 A, 1 kA, 3 kA, 10 kA.
Communication
PLA34RG offers USB, RS485 and Ethernet interfaces with several communication protocols. Modbus (RTU, TCP, Gateway), TCP/IP, HTTP (web-server), FTP, TFTP, NTP (time synchronisation), SMTP (email notifications).
Ethernet - Modbus gateway
Thanks to the built-in Modbus TCP/IP converter it is possible use the PLA34RG as an Ethernet - Modbus gateway for the connection of instruments with RS485 interfaces and Modbus RTU protocols.PLA34RG measures short term and long term flicker strictly according to the standard EN 61000-4-15.
EN 50160 PQ analysis
PLA34RG has the capability to record all parameters for the evaluation of voltage power quality according to the norm EN 50160. The EN 50160 controlled parameters and their intervals are predefined in a special template for easy setting. Via software there is the possibility to prepare a complete report for period defined by the user.
Display
Birght LCD display with white backlight shows most interesting parameters and access the minimum important settings of the instrument. Full list of measured parameters and advanced instrument setting is available via software PMS.
Web server
The instrument has an internal web-server for the remote real-time monitoring of most of measured parameters. The web-server has been designed primarly for portable instruments with web browsers and HTML 5 support.
