Phase-Over-Phase GOABS

Phase-Over-Phase GOABS

Phase-over-phase switches provide very economical sectionalizing and circuit control at tap and tie switching points. Mounted on a single pole structure in the line, their use can minimize line right-of-way requirements and significantly reduce the costs of land and equipment associated with conventional substation switching.

Phase-over-phase GOABS® utilize side-break style switches, mounted horizontal upright on aluminum and/or steel support structures. The switch is designed for maintenance-free operation in severe environmental and operating conditions. The operating effort to open and close the switch is minimal, even at higher voltages; no slamming is ever required. The switch is positively toggled when in the fully closed position, so the switch stays closed under adverse conditions, such as excessive pole deflection, vibration, and galloping conductors, without the use of blade locks or other latching devices.

Tie and Tap Switching – the economics of ‘bundling’

Major Benefits

• Minimizes right-of-way expense

• Multi-way switches reduce the number of dedicated switch pole structures

• Multi-way switches reduce initial purchase and total installed cost, compared to equivalent number of single-way switches (no line wrap)

• Multi-way switches substantially reduce installation and adjustment time, compared to equivalent number of single-way switches (no line wrap)

• Multi-way switches share other associated devices, such as interrupters, motor operator power supplies, RTU’s and communication devices, and line sensors, significantly reducing cost on a ‘per way’ basis
