The multifunctional measuring device is used for acquisition, visualization, evaluation and transmission of electrical measured variables such as alternating current, alternating voltage, frequency, power, harmonics etc.

The acquisition, processing and accuracy of measured variables and events are performed according to the IEC 61000-4-30 Class A power quality measurement standard.

Application

The multifunctional measuring device is used in single-phase as well as in three-wire and four-wire systems (with neutral conductor). The device is applied wherever comprehensive measurement of supply quality is necessary - at power utilities as well as in industry and trade sectors.

In addition to the monitoring function, the all-in-one device provides a combined recording and evaluating function: measured values can be recorded in parameterizable time intervals with various recorders such as power quality and fault recorders. Longtime data and events are evaluated directly in the device and displayed as a report according to the power quality standards (e.g., EN 50160).

Features

• Early detection of supply quality problems thanks to uninterrupted acquisition of important power parameters.
• Manufacturer-independent, comparable measured values for evaluating supply quality are obtained using standardized measurement methods according to IEC 61000-4-30 Class A (0.1% accuracy).
• Flexible “on-board” power quality logging according to EN 50160 performed directly via integrated a web server.
• Power monitoring functions for power control and as a prerequisite for energy management tasks such as identifying potential savings in the peak and base load ranges and identifying unnecessary power consumption. Recording of the fourth current channel to acquire neutral conductor current data.
• Highly precise measurements as part of energy management tasks, Class 0.2S according to IEC 62053-22 and ANSI C12.20 for obtaining power, reference, and energy measurements.
• Modbus Gateway and Master functions for easily integrating and displaying RS485 device data via a Modbus TCP network.
• Easy operation via integrated web server for parameterization, diagnosis, evaluation, and reporting.
• Interoperability through the use of standard interfaces,protocols (IEC 61850, Modbus TCP), and data formats(PQDIF, Comtrade, and CSV).
