Where is the best place to install the GMP?

The GMP should be installed in a location with the best oil flow and the lowest temperature, avoiding areas with stagnant oil or low flux. Installing the device in erroneous places can prejudice the sensor reading, and the high temperature injures the equipment. At most power transformers, the recommended places for GMP installation are:  

Local
Pros

Cons

Classification

Radiator's return valve

Great oil flux and low temperatures

The temperature could decrease below 40ºC, which could cause a mesurement error

Great

Oil sampling valves

Good oil flux and low temperature

It is necessary to change the valve for another one with two exists, to sampling the oil

Good

Radiator's entrance valve

Great oil flux

High temperature

Regular

Drain valve

Low temperature

Low oil flux

Regular


 We do not recommend installing the GMP at the power transformer top cover because the oil temperature could overpass the device operating temperature.
