LV substations

sub.net can be used to provide timely information on the transformer and feeders in an LV substation. This can be used for load balancing, demand optimization and network planning. This will allow utilities to operate their networks more efficiently and reduce costs.

A new input module allows sub.net to be connected directly to a 230/400V three phase supply. Clamp, split core or Rogowski CTs are used to monitor the transformer and feeder currents. The system can be extended to include any number of feeders. Formatted reports including graphs are sent to users via email over a GSM/GPRS network. The information from these reports may also be automatically integrated with other utility systems.

Regular reports include the phase and line voltages, transformer and feeder phase and neutral currents, per phase real, reactive powers, power factor and per feeder metered values. The real time measurements are available as maximum, minimum and average values every 10 minutes for the previous 26 weeks. For an LV substation with 6 feeders there are over 140 parameters available. Additionally sub.net can report on line faults and power quality including voltage dips, frequency, harmonics and flicker.
