But Normally in protection Trip Logic of Generators there will be Class:A,Class:B,Class:C For Class A Gen Breaker will trip for below faults U/V Stage-2 , O/V , Low Forward Power,Reverse Reactive power,Neg Ph Seq ,Over Voltage. The function of this protection device is to trip the turbine in case the condenser vacuum becomes lower than a very low preset value. The minimum setting of the relay will be 5 to 10% of its full load. In this case Generator draws power from the grid and operates as motor with the Prime mover or Turbine acting as load on the generator. When a generator is operating in the motoring mode, the machine is consuming active power from the power system and if this active power crosses the set value, then after the set time delay the relay will operate to trip the Breaker. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. 871).
