Product Profile of Power Quality Monitors

Crompton greaves, a part of the avantha group, and a conglomerate with the global footprint offers power quality monitors. The power quality monitor completes with a data logging facility measure, and stores / displays all variations in power parameters. It is beneficial in many areas like: energy and demand profiling that helps in characterizing disturbances, monitoring of transformers and motors in distribution and industrial networks to study the loading and loss patterns, monitoring of industrial networks [main incomer as well as individual feeders] for power parameters monitoring, trend analysis of pq parameters in order to identify opportunities for energy savings and demand reduction., for energy audits to increase energy efficiency. This power quality monitors are certified by certification of iso 140001: 1996.The unique features of power quality monitors are as follows:

• Measures, stores and displays voltage and current on all three phases, frequency, power factor, real and reactive power import and export and apparent power

• Data logging facility with 32 kb non-volatile memory and date and time stamp for all recorded readings

• Data logging of measured and computed parameters with suitable interface for downloading to user pc

• User settable limits for maximum and minimum threshold values for current & voltage

• Event logging / fault logging when the measured parameters are outside of set limits

• Typical data logging period for 36 days before downloading

• Factory programmable ct and pt ratios
User friendly logic, interval for data logging and duration for data logging being factory settable

• Provides alerts for uv, ov, oc, low pf, high pf.
