Surge diverters are single-stage, shunt connected devices, which are generally used for point-of-entry
(main switchboard) protection. They provide coarse protection that is suitable for the protection
of nonsensitive equipment.
In today’s highly competitive markets, surge protection is recognised as the key to solving transient related power quality problems. Small businesses, manufacturers, multinational corporations and defence research facilities worldwide have learned that their initial investments in surge protection can be quickly returned by reducing equipment damage, decreasing maintenance costs and improved system uptime.
To avoid such power problems, it is important to provide adequate protection against surges and noise. This is usually done in two steps; protection at the point-of-entry / service entrance removes the bulk of the surge (primary protection) whilst filtering and surge protection close to the equipment reduces surge further and filters out electrical noise (secondary protection).
The most effective way of providing primary protection is with the use of surge diverters such as the PW-DINVSD1R, SPD120i, SPD3Ni and SPD3Gi. Mounted at the main switchboard, these surge diverters dissipate any damaging surges safely to the mains earth, preventing damage to switchboards, wiring and more importantly, your valuable equipment. The remaining surge remnants and noise can be controlled with the use of surge power filters close to the equipment (secondary protection). These may take the form of simple 'plug-in' filters (POD, POD+ and SSFi), or 'hard-wired' filters (CSFi and DSFi) for higher currents.
