Construction :

• VIDHATA A.C Generators are available in rotating field, self excited and self regulated in Brushless and compounding system.
• The stator frame is of rolled steel with welded feet.
• Rotor core is made up of cold rolled sheets held under pressure on the grounded steel shaft.
• End shields are of cast iron construction.
• Stator is skewed for better waveform.
• Continuous damper winding fitted on poles.

Electrical performance :

• Bridge rectifier.
• Good overload characteristic.
• Can generate electricity in both directions.
• Voltage regulation within +-5% for compounding system and +-1% in Brushless version.
• Voltage adjustment range is +-5% of nominal voltage.
• Epoxy gel coating on windings after varnish for resistance against moisture.
• Good motor starting capability, the compounding system giving 2.5 to 3 times of full load capability for short duration.
• Positive voltages build up from residual magnetism.
• Sustained short circuit current in the order of 3 times of full load current.
• Voltage dips on application on full load 0.8pf on the order of 10% to 15%.

Standard Ratings :

• All ratings are based on 40degree Celsius ambient, 1000m above sea level.

Enclosure :

• • Screen protected drip proof IP 23 as per IS 4691.
