G&W Recloser Tech Connects Renewables to the Grid

As demand for clean energy increases, customers are searching for inexpensive yet efficient means for renewable integration. G&W Electric has developed a new padmounted recloser, the Viper-S (38kV, 800A continuous current, 12.5kA symmetrical interrupting, six internal voltage sensors and microprocessor control) in order to integrate renewables into the grid. Recently, a college established a need for a highly featured recloser to protect and connect a new array of PV panels to the grid. The college purchased a  25 year fixed rate agreement and needed reliable yet affordable equipment  to insure economic viability over time. After reviewing several options, the developer selected G&W’s padmounted Viper-S recloser to protect their solar investment. The cost of a padmounted G&W Viper recloser is significantly lower than a typical SF6 circuit-breaker or metal-enclosed switchgear. Most breakers are designed for higher continuous currents and fault-duty ratings, thus excessive for demands of smaller solar operations like this one. Continuous currents and fault duty ratings of the G&W Viper-S are sufficient for most applications. Additionally, the Viper-S is virtually maintenance-free. There are no gas or oil insulation levels to inspect or test on a regular basis. The only recommended replacement part is the relay battery, which can be monitored remotely and easily replaced after several years of service. Finally, the G&W solution is designed to operate for a service life of 30 years. This includes up to 10,000 full-load operations, giving the site owner the ability to open and close the circuit depending on fluctuations in utility rates. Full White Paper...

Iceland’s Geothermal Advantage

Power Sales Group Inc. CEO, Brian Curley recently traveled to Iceland, a country that takes full advantage of its constant geological activity.  “During my trip to Iceland, we toured many parts of this island country,” says Curley. “We saw beautiful sights including many geothermal and hydro energy generating facilities.” Some interesting facts emerged about this small country’s energy business: Because Iceland is a volcanic island, geothermal energy is plentiful, clean and renewable. It accounts for 25-30% of the country’s electricity needs. Hydro power is also plentiful in Iceland, accounting for almost 70% of the electricity needs of the country. In total, Iceland generates a staggering 87% of its own energy needs (when all uses are included – electricity, heat, hot water, automobile fuel, etc.). Power is so cheap and plentiful in Iceland that close to 70% of the electricity produced is used by the aluminum industry. Aluminum smelting is very power-intensive so Iceland’s resource is attractive economically to this industry, even with the cost of importing bauxite ore to the island. Iceland is exploring a project to export it’s inexpensive and abundant power to Great Britain via an undersea cable. This would provide a much needed boost to Iceland’s economy.    ...

Substation Control-cable Color Codes

For control cables with multiple conductors, there is a need for standardized color codes in order to reduce/eliminate wiring errors. The most common standard for control cables is ICEA (Insulated Cable Engineers Assocation) Standard S-7-532 and NEMA (National Electrical Manufacturers Association) Standard WC57. Within these standards, there are many “methods” and “color sequences” called out, but only a few are in common use today. The two most common are found in Appendix E, tables 1 and 2, of the ICEA/NEMA standard (and are therefore referred to as E-1 and E-2). Earlier editions of the standard had the color sequences located in Appendix K, so some people still refer to K-1 and K-2 color codes. E-1 is the most commonly specified by utilities. For application where NEC is applicable (typically commercial/industrial applications), E-2 is commonly specified. At Power Sales Group Inc., we find Southwire, with it’s many years of experience in implementation and customer service,  to be experts in control cable application.  For more information on control cable systems and Southwire services, please contact us...

Preventing Switch Failure

Disconnect switches have the important role of isolating circuits and equipment on any modern power grid.  When a switch is open, operators can easily confirm this; however, it is nearly impossible to visually confirm a perfect closed connection. Improperly seated switches have led to switch burn outs and power outages coupled with high costs for utility companies. The idea of a disconnect switch may seem simple, but from the ground, it’s surprisingly difficult to determine if a switch is properly functioning. The issue is the switch blade must establish a high degree of contact pressure between the switch jaws in order to generate the necessary current. Due to inclement weather, defective equipment or operator error, a switch may remain partially open or un-rotated unbeknownst to technicians, causing burnouts and failures. Southern States has solved this issue with a new switch technology called MACI or Magnetically Actuated Close Indicator which provides unambiguous visual confirmation for disconnect switches. A colorful red indicator provides a ‘closed confirmation’ from 100 ft. away MACI provides an unambiguous, binary indicator, which only shows when blade is fully seated and rotated. MACI has magnetically coupled linkage, which ensures the indicator never interferes with switch operation even in severe weather. Watch the video below to see MACI in action.   Highlights -Visibility up to 100 ft. -Magnetic switch that does not interfere with mechanism -Unambiguous binary signal -Retrofitted to any vertical break or any double end break switch -Rated for 245kV and above / 115kV available 1Q16...
