  • Combing GDTs and MOVs for Surge Protection of AC Power Lines (.pdf)
    reference is IEEE C62.41-1991 entitled "IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits" (formerly IEEE Standard 587).This standard defines the open circuit voltage and short circuit current waveforms which can be expected to occur on AC power lines of 1000 Volts (RMS
  • Surge Protection Technology Used in Power over Ethernet (PoE) Protection 9.(.pdf)
    and PoE+ in open-air environments are subjected to large surge currents, and protection must be installed to prevent damage. This paper will outline the components, standards and grounding used in PoE protection. The two main standards for PoE are IEEE 802.3af and 802.3at. These standards relate
  • Alltec Protection Pyramid
    lines can carry extreme voltage transients many miles. It is prudent that certain steps be taken to protect people, equipment, and buildings; the TerraEval TM Advanced Solution Assessment engineering service is specifically designed for this purpose. Alltec's three-step Protection Pyramid TM
  • Data Line Protectors (.pdf)
    be protected against overvoltages that can exceed 1500 V and surge currents up to 50 A. Data Line Reference Circuit Figure 3.57 shows how a SIDACtor device is used to protect low voltage data line circuits.
  • The ABCs of Littelfuse Multilayer Suppressors (.pdf)
    . What circuit or component requires protection and, therefore, to what level must the transient be suppressed. Multilayer Suppressors are most often applied to low voltage (<50VDC) systems on power supply, signal, or control lines in order to suppress ESD, EFT, Surge, or other transients
  • When lightning strikes wind turbines
    for lightning strikes. Operators of wind-turbine installations (WTIs) of course want to minimize downtime and repairs. So well-designed surge protection is a necessity for this equipment. WTIs have a lot of technology crammed into a small space. A transformer station inside the tower adapts the generator
