Abstract
A system for monitoring and treating transformer oil within an on-line electric transformer may include an oil filtration system using a first filter medium that removes acids dissolved in the transformer oil and a second filter medium that removes moisture from the transformer oil. A control and monitoring system may include a hydrogen sensor, a moisture sensor and a control module that receives and displays information and may be used remotely and wirelessly to control the systems. A monitoring dashboard may be positioned remotely and wirelessly receive and display information.
Claims20
A system for monitoring and treating transformer oil within an associated on-line electric transformer comprising:
- (A) an oil filtration system comprising:
- (1) a first filter container comprising a first filter medium that removes acids dissolved in the transformer oil from the transformer oil;
- and,
- (2) a second filter container comprising a second filter medium that removes moisture from the transformer oil;
- (B) an oil movement system that moves the transformer oil from the associated on-line transformer, through the transformer oil filtration system, and back into the associated on-line transformer;
- the oil movement system comprising a pump;
- (C) a housing located near the associated on-line electric transformer that houses the first and second filter containers and the pump;
- and,
- (D) a control and monitoring system that:
- (1) comprises a hydrogen sensor that:
- (a) is positioned within the housing;
- and,
- (b) senses the amount of hydrogen in the transformer oil;
- (2) comprises a moisture sensor that:
- (a) is positioned within the housing;
- and, (b) senses the amount of moisture and temperature of the transformer oil;
- (3) comprises a control module that:
- (a) is mounted to the housing;
- and, (b) receives and displays information from the hydrogen and moisture sensors;
- (4) comprises a monitoring dashboard remote from the housing that wirelessly receives and displays information from the hydrogen and moisture sensors;
- (5) determines parts per million (PPM) of moisture in the transformer oil;
- (6) determines the temperature of the transformer oil;
- (7) determines saturation of moisture in the in the transformer oil;
- (8) sets off an alarm or alert when certain predetermined operating conditions occur;
- and,
- (9) posts the information from the hydrogen and moisture sensors on an internet based data center.
