CORRECTIVE ACTION
11. PARALLEL GENERATORS DO NOT DIVIDE REACTIVE KVAR LOAD EQUALLY. (Circulat-
ing Reactive Current Between Generators.
Step 1. Verify that the tap on R25 is not set to the minimum position.
If the tap is set to the minimum position, adjust R25 to obtain the required droop.
If the tap is set properly, proceed to step 2.
Step 2. Verify that the Parallel CT provides the required 3 to 5 A secondary current.
If the CT does not provide the required 3 to 5 A secondary current, refer to paragraph 3-
3.
If the CT does provide the required 3 to 5 A secondary current, proceed to step 3.
Step 3. Verify that the paralleling CT's polarity is correct.
If the CT's polarity is incorrect, reverse the CT secondary leads.
If the CT's polarity is correct, proceed to step 4.
Step 4. Verify that the paralleling CT is in the correct generator phase (line).
If the CT is not in the correct phase, place CT in correct line.
If the CT is in the correct phase, proceed to step 5.
Step 5. Check that all paralleled generators have the same type of sensing (either single-phase
or three-phase).
If all paralleled generators do not have the same type of sensing, adjust R25 to compen-
sate.
If all paralleled generators do have the same type of sensing, proceed to step 6.
Step 6. If the above steps fail to correct the malfunction, replace or repair the voltage regulator
as necessary.
