Transformer Oil Dielectric Strength Test

1. The Summary

Insulation oil test machine is produced according to the National Standard GB-86 “Determination Method for Dielectric Strength of Transformer Oil”. The parameters are set in advance with the adjusting switch and then the instrument strictly works on the basis of the preset parameters. After doing one test, the results can be printed if you want. This instrument has a series of characteristics, such as strong anti-jamming, simple operation, sound light warning.

2. Technical Index

Relative Series:
VFD series: Insulation Oil Purifier Series
TF series: Turbine Oil Purifier Series 
LV series: Lubrication Oil Purifier Series
GER series: Used Engine Oil Regeneration System

VFD series: Insulation oil purifier System specialize in purifying branded oil, insulation oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.
TF series: Turbine oil purifier system is particularly suitable for purifying turbine lubricating oil. It  also applys to treat hydraulic, coolant oil and other lubrication in which contain large of water, vapor, impurities, sludge, dielectric and colloid. It can eliminate them effectively and efficiently.
LV series: Lubrication Oil Filter System are suitable especially for purifying and restoring hydraulic oil, machine oil, coolant oil and various other lubrication oil.
GER series: Used oil regeneration system is suitable to regenerate used internal-combustion engine oil including diesel engine oil, gasoline engine oil, and used hydraulic oil, other used lubrication oil of machinery.

Relative Parts:

1. Foam Level Detector
When there is foam in the tank and foam reaches a certain level (resetable), a signal will be sent to the magnetic valve, the magnetic valve will automatically shut on. The foam will be removed quickly. After removing foam, the magnetic valve will shut off.
2. Digital Vacuum Gauge (Pirani gauge)
Display Type: Digital
Accuracy: ±1.0%
3. Digital Hygrometer(water or moisture in oil tester) On-line type
Measure Scope: 0—100 PPM
Display Type: Digital
Output Signal: one is PPM, the other is temperature.
4. Digital Flow Meter Display Type: LCD
Mode: 1) accumulative total value 2) online flow value 3) accumulative total value for each time (reset adjustment)
