Multi-functional 3 phase meters

These devices are designated to measure and monitor line-to-line and phase voltages, currents, active and reactive powers, true power factor, THD for both voltage and current one- and three phase LV, HV and VHV networks and sense the temperature inside a switchboard. 

Characteristics

• true root-mean-square values of voltage and current (TRMS)
• active and reactive power, four quadrant presentation in compliance with IEC375
• both true power factor (PF) and power factor of fundamental harmonics (cos fi)
• Total Harmonic Distortion and harmonics of voltage and current up to the 20. order
• built-in temperature sensor

  

• single-phase, two-phase, three-phase or Aron connection
• direct & undirect voltage connection
• optional remote RS-485 communication link
• panel mounted (SML) or DIN-bar mounted (SMM) version

SMN add-ons:

• calcualtion and displaying of fourth current (PEN)
• evaluation of maximum average  3-phase power
• internal real time clock
• external (clamp-on) current probes with split core

Data Acquisition and Processing

Devices can be optionally assembled with communication line (RS232, RS485) and support communication over ethernet or with modem with external convertors.

RETIS

Basic software equipment for management of  KMB systems devices in MS Windows environment. RETIS provides features for logging of actual measured values from multiple devices, visualization and complete configuration. Downloaded data can be stored in archives, processed statistically or exported for further work. Program uses serial lines or Ethernet for communication and supports various media converters (modems etc.).
