Electromechanical Problems:
Excessive voltage drop
Reduced equipment lifespan
Utility and facility energy losses
Internal electricity infrastructure stress

Our Process
Through proper site and power analysis our technicians will conduct system studies involving harmonic studies, power factor studies, load flow studies, power flow studies, transient studies, power quality studies and on-site measurements. This site analysis is usually conducted over a minimum of 7 days with little to no interruption to site operations. The data collected allows our technicians to design and cater for the sites unique electrical profile and provide key information on the cost and expected Return of Investment.

Most commercial and industrial sites suffer from poor power factor which is a measurement of a sites electrical efficiency. Power factor is often defined as the ratio of the real power flowing to the load to the apparent power in the circuit. Power factor is displayed as a dimensionless number between 0 and 1 (frequently expressed as a percentage, e.g. 0.8pf). Here in Australia anything under .85pf is usually considered to be poor power factor with most states requiring a level of .90pf or above to avoid penalties.

The highest contributor to poor power factor is the ever increase of non-linear loads. Devices that exhibit non-linear characteristics include transformers, conductors, motors, fluorescent light ballasts and computer equipment. Statistics indicate that non-linear loads will double in the next decade with the additional power required creating electromechanical and/or financial problems.

Financial Problems:
Fees and penalties for energy losses
Increased replacement costs
Higher cost of infrastructure installation
Possible facility downtime
