Single- and three-phase surge protection
September 2011
Electrical Power & Protection
The single- and three-phase tripconnect lightning and surge protection unit with programmable delay is used to protect electrical installations from damage due to lightning or large fluctuations in supply voltages. When the supply voltage is too low or too high, the unit will disconnect power to the downstream equipment, it will automatically restore power after a preset delay when the supply returns to acceptable levels. Modules are available for loads up to 115 A.
These units perform cycle by cycle RMS voltage measurements incorporating similar technology and design to that of an automatic voltage regulator with devices installed between the incoming supply and the DB board or equipment. Typically these protection systems are suitable for domestic, commercial and industrial applications. The three-phase tripconnect system is particularly useful when protecting large equipment such as motors, pumps, refrigeration and air-conditioning systems.
