*1
Note: Parameters specified in application with mineral oil.
*2
Note: Accuracy is quoted for the detectors under factory calibration and test levels.
Gas-in-oil measurements may be affected by sampling and/or oil type.
*3
Note: Whichever is greater.
*4
Note: Given in ppm.
*5
Note:
Based on testing carried out using VOLTESSO™ 35 mineral oil over a ¼ in. pipe
run of 10 metres or less from oil supply or return valve to product connection
point, and on transformer oil supply valve volumes of 200 ml or less. For oil
temperatures colder than
−
10 ºC, GE recommends the use of heat trace cabling
on piping. Low oil viscosity reduces oil flow.
