Network Analysis System

The quality of the energy supply is an important component of a functioning IT system. There are UPS protection systems available which can help. The quality of the energy supply from different power supply companies in conjunction with different IT applications may vary extremely widely. To this end, Rittal offers the network analysis system. It may be ideally integrated into the Power Distribution Rack PDR, where it will analyse the power infeed. The system performs network quality measurements to EN 50 160. It has a generous illuminated display for the direct retrieval of measurement results. Furthermore, all information is available in the network via the integrated WEB server. Evaluation software is also included with the supply, which is capable of reading the measurements via the network and analysing them to DIN EN 50 160 and EN 61 000-2-4. The electronic measuring device, which is equipped with 4 current and voltage inputs, records and digitises the effective values (RMS) of currents and voltages in a 15 – 75 Hz network. Based on the scanned values, the built-in microprocessor calculates the electric variables. For measurement in the three-phase system, the relevant voltage may be defined as a conductorzero or conductor-conductor voltage. This voltage is used by the Rittal network analysis system to measure harmonics and to log transients and events, and for the flickermeter. Measurement functions: • Automatic adjustment to a network frequency of 15 … 75 Hz • Measurement intervals of 10 (50 Hz) or 12 (60 Hz) period (200 ms) • Contiguous scanning and calculation of the following measurements: Voltage L-N, neutralpoint displacement voltage and asymmetry L1...L3, voltage L-L, frequency, current, aggregate current L1...L3 and L1...L3+N, active power, reactive power, apparent power, power factor, distortion reactive power, fundamental power, cosphi, phase shift, work of main and auxiliary system, reactive power demand (capacitive and inductive) 1..50 harmonic of current and voltage, distortion factor (THD) of current and voltage, short- and long-term flickermeter readings, level of ripple-control signals.
