Traditionally, shunt reactors utilising oil-paper insulation systems are used at transmission levels, but due to technological developments, material improvements and changing environmental requirements nowadays dry-type air-core shunt reactors are used up to a system voltage of 420 kV or even 500 kV .
This relay system will securely isolate the shunt reactor from the line in case of a flashover in one of the shunt reactor phases along the winding and, for transmission class reactors consisting of two separately mounted sub-reactors, across the intermediate insulators to ground.
In the case of 3‑phase unit a complete 3‑phase shunt reactor must be used as a spare. If the shunt reactor is constructed as three separate single phase units, a complete phase must be replaced in the event of a failure.
A 420 kV shunt will typically be constructed in two reactor columns of two windings connected in series. To have full availability as soon as possible after a failure event, it’s recommended to attain one complete phase, which means 4 windings or two columns, as a spare.
Typically, 420 kV dry-type shunt reactors are designed as single-phase units. Each of the phases is divided into two reactor towers and each of these towers is again split into two series connected coils. Fig. 2 and 3 are showing the basic layout of a 420 kV shunt reactor installation consisting of 12 sub coils.
Air Core Shunt Reactors are connected directly to high voltage transmission lines and provide a compensation for the reactive power on transmission systems, eliminating the need for oil insulation and thereby the risk of fire.
