Current measurement at high voltages has become a big issue in this age of Smart Grid and FERC regulations. The CMD® II revolutionary technology measures current on high voltage systems with zero foot print, no solid insulation to ground and no batteries. It uses 5.8 GHz communication technology to transfer data securely, economically and reliably from the high voltage system to ground potential in real time....(continued)

Transmission Smart Grid - A Smart Grid Oversight?

Smart Grid is a name that has been given to describe the modernization of the transmission and distribution grids with the goal of increasing reliability, integrating multiple energy sources, and conserving energy. This involves a greater use of renewable energy sources, real-time monitoring and automation of power flow, as well as more active conservation efforts by the actual user of the power....(continued)

Where the Wind meets the Grid

There is a reason Southern States unique and purpose built products are strongly entrenched and widely used in new wind farm construction and collector station upgrades. The reason so many wind farms use Southern States products is that they solve the toughest problems in their application.

Wind power generators are large induction motors which can degrade power quality on the grid. Capacitor banks are a major part...(continued)

RLSwitcher® Shunt Reactor Switch

Switching shunt reactors is one of the most difficult switching duties and can shorten the life of both the switching device and the reactor. The RLSwitcher®, available at 38 kV through 245 kV, is designed specifically for switching shunt reactors. Its' unique interrupter design minimizes reignitions and their...(continued)

The LLS-I 72-2000 Load and Line Interrupter is an ideal attachment for a vertical break switch adding the capability for breaking full load current (2000 Amperes), line charging currents (300 Amperes), and loop splitting currents (2000 Amperes). The LLS-I, designed specifically for 72 kV and below, will mount on any manufacturer’s...(continued)

All of his friends and colleagues at Southern States wish to inform all of his many colleagues and friends throughout the electric utility industry that Bennie Fletcher has reached a truly historic milestone, 50 years of dedicated service at Southern States.

Abstract—Circuit switchers are designed for, tested, and used in substation protection schemes to clear transformer internal faults as well as back-up protection of the transformer secondary circuits. If the circuit switcher fails to successfully clear the fault, it is common for a circuit breaker, upstream from the substation, to perform the interruption. The utility may use a distance...(continued)
