ELECTRICAL DIAGNOSIS - DETERMINING THE TYPE OF
ELECTRICAL PROBLEM
Electrical problems can be in the generator, wiring, or in the Whisper Controller. Determine which as follows:
1.
Wind generator will not start (blades turn slowly as if the diversion switch is engaged):
On a day of
moderate wind, disconnect the three wires from the wind generator one at a time at the Whisper Controller. If the
wind generator starts, the wire that allowed it to start leads to a failed component in the Whisper Controller. Call the
factory or the distributor to replace the failed component.
OR
2.
Wind generator still does not start:
On a day of moderate wind, disconnect any two wires. If the wind
generator starts, the problem is most likely in the Whisper Controller. Go to
Table: Symptoms of Whisper
Controller Problems, page 33
. If the wind generator still does not start the problem is in the tower wiring or the
wind generator. Go to
Table: Symptoms of Electrical Problems, page 32
OR
3.
Wind generator is running, but may have an electrical problem:
As directed below
,
use a
voltmeter to read the voltage across the leads and see the voltmeter test section below as a guide to possible
problems.
Voltmeter Test
1. 1. Voltage increases and decreases slowly relative to the wind speed across all combinations of paired wires = Every-
thing ok.
2. No voltage across two wires = One wire from wind generator not carrying power. Check in order: Check the tower
wiring and Whisper Controller connections to insure proper wiring. If the wiring is correct contact authorized dis-
tributor or factory for further assistance.
3. Voltage significantly higher across two wires than the others = Contact the distributor or the factory, possibly a
shorted diode.
4. Voltage significantly lower across two wires than the others = Bad connection at wind turbine voltage connections or
faulty stator winding. Report this failure to your distributor or the factory.
5. Should these results appear inconclusive in determining the problem proceed directly to
Table: Symptoms of Elec-
trical Problems, page 32,
or
Table: Symptoms of Whisper Controller Problems, page 33.
