During its operation of generating, transmitting and distributing power transformers give out heat which is absorbed by insulating oils. This oil has a tendency to absorb moisture from windings which leads to gradual deterioration of dielectric strength. Our filtration systems provide economical and efficient methods of purifying this lubricant. The unit consists of:
- Filter Unit,
- Indirect system of Oil Heating,
- Vacuum Dehydration / degasification Unit
- Condenser and condensate receiver
- Feed and delivery pump
- Piping & Valves
- Control Panel
Components of Plant
The filter unit is a coarse strainer with a wire mesh filter element for retaining solid particles and a powerful magnet for retaining magnetic particles. It has round filter paper discs held under spring compression. Specially designed heaters with low watt density heat the auxiliary heating oil, which in turn heats the transformer oil maintaining a temperature of 70-80 C. The cylindrical external pressure vessel is fitted with various shallow drip trays and a specially designed spray pipe to increase surface area. The vapor from dehydration chamber is condensed in a condensate receiver of welded M. S. construction. There are feed and delivery pump of rotary gear type coupled directly with motors. Water Separator Collect the water produced. A centralized control panel has indicators for all electrical devices.
- Imported thermostat
- Thermometer for measuring temperature
- Pressure & Vacuum gauges
- Flow control indicator
- Electronic Float Control
- Electrical instruments, voltometers and ammeters
- Electrical overloads and overload releases for safety of motors.
