6.2.2.3. Generator check by an electronic oscillograph

The form of a curve of the straightened pressure of the generator

I – the generator is serviceable;

II – the gate is punched;

III – breakage in a gate chain

The oscillograph allows under the form of a curve of the straightened pressure of the generator precisely and quickly to check up its serviceability and to define character of damage.

For check rotate a rotor of the generator with frequency of 1500-2000 mines-1, feeding a winding of excitation from the storage battery, but from a clip «30» battery disconnect.

At serviceable gates and a winding статора the curve of the straightened pressure has the sawtooth form with a uniform teeth.

If there is a breakage in a winding статора either breakage or short circuit in rectifier gates, the curve form sharply varies: uniformity of a teeth is broken and there are deep hollows.
