Power Quality
Small businesses or large corporations cannot afford to take risks with power in today’s climate.
NDY specialises in solving poor power quality problems, which threaten life, safety, the performance of critical systems and the reliable operation of electrical equipment, including:
- Plant equipment protection
- Low power factor
- Harmonic problems
- Power System stability
- Health risks associated with EMC
- Earthing Issues
“Field studies indicate that the frequencies of power quality problems are intensifying with each succeeding generation of technology.”
The growth of power related problems can be directly linked to the growth of sophisticated and complex electronic loads - which in turn are frequently installed in modern office and IT environments and may not benefit from wiring enhancements and generic power protection strategies alone.
NDY offers expert advice on all forms of power problems – to ensure the safe
and reliable distribution of electricity. Our Power Quality engineers utilise
sophisticated test equipment and power signature spectrums to determine the
origin of power disturbances and offer engineered solutions to achieve the desired
level of power system correction.
Our clients for this type of service include small businesses, telecom carriers
responsible for critical data technology centres, industrial & resource
sector sites as well as infrastructure such as port facilities.
