Class Description
Common information captured during transformer inspections and/or diagnostics. Note that some properties may be measured through other means and therefore have measurement values in addition to the observed values recorded here.
Attributes
| Name | Type | Description |
|---|---|---|
| bushingTemp | Temperature | Bushing temperature. |
| dga | String | Dissolved Gas Analysis. Typical values are: Acceptable, Overheating, Corona, Sparking, Arcing. |
| freqResp | String | Frequency Response Analysis. Typical values are: acceptable, slight movement, significant movement, failed, near failure. A graphic of the response diagram, which is a type of document, may be associated with this analysis through the recursive document relationship of the ProcedureDataSet. |
| furfuralDP | String | Overall measure of furfural in oil and mechanical strength of paper. DP, the degree of polymerization, is the strength of the paper. Furfural is a measure of furfural compounds, often expressed in parts per million. |
| hotSpotTemp | Temperature | Hotspot oil temperature. |
| oilColor | String | Oil Quality Analysis-Color. |
| oilDielectricStrength | Voltage | Oil Quality Analysis-Dielectric Strength. |
| oilIFT | String | Oil Quality Analysis- inter facial tension (IFT) - number-Dynes/CM. |
| oilLevel | String | The level of oil in the transformer. |
| oilNeutralizationNumber | String | Oil Quality Analysis-Neutralization Number - Number - Mg KOH. |
| pumpVibration | String | Pump vibration, with typical values being: nominal, high. |
| status | Status | |
| topOilTemp | Temperature | Top oil temperature. |
| waterContent | String | Water Content expressed in parts per million. |
