Power Factor Monitoring Device

Power-factor correction equipment is used by major electricity consumers to lower their electricity bill. The main aim of the correction is to ensure that your maximum kVA demand is measured at unity power-factor. Power-factor correction systems are subject to various problems arising from capacitor, contactor or any other component failure and can go undetected for months. These conditions can contribute to a major increase in maximum demand, which inevitably leads to financial losses.

The solution to this situation is 24 hour online monitoring ensuring correct system functionality and enabling quick response to system component failure minimizing financial losses.

Product summary


The PFMD measures the supply independently from the PF Controller and reacts whenever an alarm condition arises. The alarms are monitored by a server, are logged and forwarded to the relevant personal on standby. Reaction can vary from a simple inscription in the database to immediate response from personnel on standby. The personnel on standby will receive the alarm SMS containing all relevant information to notify them of emergency call-outs.


Monthly System Reports

Monthly system reports are issued and contain critical information concerning the functionality of the power-factor control system. The report includes billing information concerning the Maximum demand in kVA and the estimated savings. The statistical component of the report covers important information about step counters alarm conditions and fault counters.
