SHUNT REACTORS
SHUNT REACTORS
|
|
Shunt reactors are used in order to compensate capacitive reactive power generated by long and lightly transmission lines, thus allowing the flow of more active power through the system. Shunt reactors are normally connected to the tertiary winding of the main transformer.
In high power and high voltage systems, shunt reactors should be used with RC filters because in such systems switching transient voltages are extremely high and that's why switching devices may be damaged.

INSTALLATION
The height and the diameter of the reactor can be adjusted to customer specific needs in order to meet unusual space requirements.
Complete installation guidelines are provided with the reactors in order to meet required magnetic clearances on close metallic structures. Each reactor is supplied with an INSTALLATION GUIDELINES that specifies minimum magnetic clearances for the reactor.
SUPPORT STANDS
Aluminum, hot dip galvanized steel or concrete support stands are designed for specific applications.
LOSSES
All Hilkar Electric reactors are computer designed in order to minimize investment and operating losses.
