Does voltage across the load controlled by a saturable reactor vary with load power factors?
Yes, in approximately the following values: Thus, on an 80% power factor load that the output voltage across the load will be approximately 76%. Where a nominal 600 volt line voltage appear across the load the line voltage would be .76 x 600 volts or approximately 456. In this instance, 460 volt rated equipment may be used. In the even the output voltage is below a usable range, you can use an auto transformer to boost the line voltage so that the resultant voltage appearing across the load will be the desired value.
