Surge Protection

Oil and gas facilities require surge protection strategies that match the complete electrical and instrumentation architecture. Long outdoor cables, remote field devices, control systems and communication networks can create multiple…

A fuse symbol in a circuit diagram identifies a fuse in the protected current path. The graphical form helps you locate the protective device, but the symbol alone does not…

Marine low-voltage electrical systems require a dedicated surge protection evaluation approach. Unlike standard building installations, shipboard systems may connect to shore power, operate with generators, include long cable routes and…

Airfield Ground Lighting (AGL) systems, including runway lights, taxiway lights and approach lighting circuits, operate across exposed outdoor areas with long cable routes and distributed field equipment. These characteristics create…

Modern elevator systems rely on electronic control panels, variable frequency drives (VFDs), communication interfaces and long cable routes between machine rooms, shafts and field devices. These components can be sensitive…

Industrial standby generators and diesel generator systems require a coordinated surge protection strategy. The protection design should consider the complete backup power path, including utility supply, automatic transfer switch (ATS),…

Selecting an AC surge protective device for a main distribution board is not simply a matter of choosing the largest kA value. The correct MDB surge protection solution depends on…

A PV inverter RS485 communication cable may connect an outdoor inverter to a data logger, monitoring cabinet or control room. When that cable is exposed to surge risk, the main…

This guide answers one specific engineering question: how should a DC surge protective device be connected inside a solar combiner box? It focuses on the SPD branch position, DC+ and…
