penstock

Each generator is supplied with water by an individual penstock.

Other workers would have to leave the penstock and get fire extinguishers from outside.

Also extant is a penstock that carried water to the plant.

In the photograph above, the left-hand penstock is the newer one.

Due to the efficiency of the scheme another penstock pipe was added in 1919.

Above the wheel is a cast iron penstock now permanently closed.

Soon after the dam began operations in 1931, its penstock partially collapsed.

Much investigation went into the accident resulting in the almost complete redesign of the penstock.

Sometimes the final approach of the water to the wheel is along a lengthy flume or penstock.

Behind that, it drops over a 160 metre long penstock to the hydroelectric power plant.

Construction on the redesigned penstock was completed in 2009.

In mountainous areas, access to the route of the penstock may provide considerable challenges.

"It should be foggy in the next hours," Charles Penstock said.

The turbine - imagine a huge propeller - sits at the end of the penstock.

It was taken out of service in December 2000 after the rupture of a penstock.

A large pipe (the "penstock") delivers water to the turbine.

Just before reaching the power house and its eight turbines, each penstock splits into four branches.

Each turbine is fed by a penstock, in diameter, that tunnel through the right side of the dam.

Two surge chambers were built in the powerhouse as well, and a penstock connected to each chamber.

In 1963 the dam had to be repaired because its penstock had collapsed.

The guide vanes therefore act as the valves between the penstock and turbine.

"It would help if we knew what the weather would be for the next few hours," Charles Penstock said.

The conduit bringing high-pressure water to the impulse wheel is called the penstock.

The water from the dam flows through a penstock to a power generation plant in the adjacent town of Readsboro.

The failure appears to have been due to several factors including the poor strength of rock surrounding the penstock at the rupture location.
