The Types, purpose and function of Oil level Gauge (level

The Types, purpose and function of Oil level Gauge (level

  Prismatic Oil Level Gauge: When the oil level is above the cone, the gauge is black and when the oil level is below the cone, the gauge window is red. With light falling on the gauge window regardless of the color of the transformer oil will indicate either black or red to ascertain the level of the oil in the conservator tank.

How to read transformer conservator level gauge Electric

  How to read transformer conservator level gauge. Can someone tell me how to properly read a gauge for oil level in a transformer conservator tank that is marked by degree temp Celsius. The gauge is calibrated to read normal @ 20 deg C. As temp increases, oil

Transformer temperature, oil level and pressure gauges

Transformer temperature, oil level and pressure gauges

  An oil level gauge is required so that the correct oil level can be maintained. There is usually a mark on the gauge that indicates the 25°C level, which is the proper oil level at that temperature. Maintaining the proper oil level is extremely important because if the oil level falls below the level of the radiator inlet, flow through the radiator will cease and the transformer will overheat.

3.1 Oil temperature indicator (OTI) Oil temperature indicator with digital and analog output (eOTI) These devices are designed to measure the temperature of the insulating oil inside of power transformer tanks. It’s possible to fit up to 5 change over micro switches suitable to

WTI and OTI of Transformer

WTI and OTI of Transformer

WTI and OTI of Transformer. The WTI means winding temperature Indicator and OTI means Oil Temperature Indicator which indicates the winding temperature & oil temperature of the transformer and operates the alarm, trip, and cooler control instrument operates on the principle of thermal imaging and it is not an actual measurement.

Transformer temperature, oil level and pressure gauges

Transformer temperature, oil level and pressure gauges

Instead, it measures the top oil temperature plus a temperature gradient produced by a small heater surrounding the thermometer bulb. This heater is connected to a current transformer on one of the phases of the secondary leads, so as the secondary load increases, so does the current through the heater resistance.

The temperature measured on the gauge is the top oil temperature and sometimes a simulated winding temperature. Both of these measurements will indicate the temperature rise plus the ambient. The important point to note here is that the nameplate temperature rise is not the temperature one sees on the temperature gauge of a transformer when

Magnetic Oil Gauge (MOG) in Power Transformer Electrical

Magnetic Oil Gauge (MOG) in Power Transformer Electrical

  Magnetic Oil Gauge (MOG) in Power Transformer. It is essential that oil level in the conservator tank to be maintained at a pre determined minimum level. Therefore all large Transformers are fitted with a Magnetic Oil Level Gauge, which are incorporated with mercury switches which operates when oil level in the Conservator goes below minimum level and generate an alarm or Trip contact.

TRANSFORMER OIL FILLING AND TESTING PROCEDURE

TRANSFORMER OIL FILLING AND TESTING PROCEDURE

Fill the oil up to the desired level in the oil level gauge. The level should coincide with the equation of oil level against temperature mark in the oil temperature gauge. The temperature gauge is furnished to indicate to top liquid temperature in the tank. After filling of Transformer, Oil Circulation follows.

Transformer temperature, oil level and pressure gauges

Transformer oil level indicator Temperature controls are required in order to turn on and off the cooling equipment. These controls are usually combined with a visible dial type gauge that measures ‘winding temperature’. This is really a misnomer because the gauge does not actually contact the winding. Instead, it measures the top oil temperature plus a temperature gradient produced by a small
