Protecting against electrical surges - 20 things you should know
07 October, 2010 by Paul StathisAll electrical installations are subject to a frequently distorted electricity supply. Uncontrollable anomalies such as lightning strikes and electromagnetic interference can and do distort the AC supply into buildings. Some can be catastrophic, destroying equipment from a single surge, while others can be too small to notice on their own, but have a cumulatively detrimental effect on equipment that inexplicably fails over time. But there are simple ways to deal with these challenges.

Cirprotec lightning, surge and overvoltage protection
16 April, 2010 byThe Cirprotec range of lightning, surge and overvoltage protection products includes DIN-style surge diverters, high-capacity (kA) surge diverters for incoming main switchboards and data and communication surge diverters for I/O and control applications.
PD Devices MDSP3 surge protector
16 December, 2009 byThe PD Devices MDSP3 series surge protector devices provide protection against incoming high-voltage spikes and slower rise time disturbances for three-phase 415 V circuits. They are designed for use on incomers at main switchboard level and can be combined with PD devices suitable for lower transient capacity at sub-distribution board level.
Harmonics - fighting the enemy from within
01 December, 2009 by Paul StathisThe push for ‘greener’ electricity through more sophisticated electrical technologies has, in many cases, increased the negative consequences of harmonics on our electrical infrastructure. Electronic ballasts for lighting, switchmode power supplies for PCs and variable speed drives for motor controls are becoming ubiquitous in our homes and workplace. But while they’re improving our energy efficiency, they’re also making the electricity supply dirty.
Active harmonic filter
02 September, 2009 byThe Schaffner ECOSine Active 60 A filter is designed for harmonics mitigation in commercial and industrial electrical installations where loading can change rapidly and unpredictably.
