ASM 111

Description

ASM-M111 intelligent measuring center with the ability to measure, record and communicate electrical parameters in three-phase and single-phase networks
ASM from a measurement perspective:
• Ability to measure and display voltage and current of three-phase and single-phase and zero current (with fourth CT) with an accuracy of 0.2%
• Measuring and displaying apparent power, active and reactive power in two directions with an accuracy of 0.3% (produced or consumed / inductive or capacitive)
• Measuring and displaying the power factor for each phase separately
• Measure and display frequency with 0.02% accuracy
• Energy measurement with the ability to define 4 different tariffs.
• Measure and display the internal temperature of the device
• Ability to connect external PT100 sensor to measure temperature
• Ability to measure and display demand
• Ability to adjust the conversion ratio of CT and PT

ASM in terms of power quality:
• Measurement and display of THD for voltage and current of three phases (each phase separately)
• Measuring and displaying the amount of harmonics up to the order of 31 as a bar and percentage (each phase separately)
• Detect and record voltage sag and voltage swell
• Ability to measure and display power quality analysis parameters on request

ASM in terms of protection functions:
• Over Voltage detection
• Under Voltage Detection
• Over Current detection
• Demand Control
• Reverse power detection (reverse power detection in motor and generator equipment)
• Over THD detection
• Two adjustable digital inputs
• Two adjustable digital outputs (contactor relay)

ASM from the perspective of data logger:
• Ability to store 500 events (full function of protection functions, change settings, turning the device on, resetting energy and alarms, etc., digital input stimulation, digital output function, power return)
• Ability to store the complete waveform of currents and voltages of each phase for 1 second (50 cycles) for 6 events with a sampling rate of 20 samples per cycle (Oscillograph)
• Ability to store measured values at an adjustable rate (from seconds to hours) for one year
• Ability to trigger waveform recorder manually, with digital input, or in case of protection functions
• Ability to report in Comtrade format
• Ability to read and store the measured values through the USB port on the device
