Surge Protection Devices
Surge Protection Devices
SPDs are to protect sensitive Electrical & Electronic equipment from transient overvoltages that are present on low-voltage power supply, data & communication lines. A Surge is a short-duration high-voltage impulse appearing on power mains or low-voltage signal/data/power/ communication lines.
Various causes of Surge / transient overvoltage:
Lightning, rise in ground potential, electromagnetic radiation, switching of heavy equipment & loads, operation of fuses & circuit breakers, utility grid switching, power factor correction actions, power cycling of inductive loads, electrostatic overvoltage (ESD), Nuclear Electromagnetic pulses(NEMP), the sensitivity of components & devices, miniaturization of electronic components inheriting from valves to transistors to ICs to microprocessors.
Effects of surge / Transient overvoltage on the electronic components:
Destruction – of PCBs, components interference with operation – erratic operations, memory loss, program malfunctions, data & transmission errors, Premature aging of components – Life reduction of components.
Use of SPDs will help you in:
- limit discontinuities of service and their costs
- Reduces down time
- Increase the productivity
- Increase the life duration of your equipment
- Improves the quality and precision of your process
- Result = savings +improved service quality
