Microprocessor controlled, saves operator's time.
Recall of individual tests including breakdown voltages,
  averages,  the test number, all displayed digitally.
Emergency exit allows the operator to quit the process.
Safety interlock on high voltage test chamber & zero start.
The sets are available with printer port &/or Rs.232 interface.
Equipment to enable easy, accurate & safe measurements.

 
Microprocessor Based Oil Test Set Semi Automatic
  Application
These test sets are used for determining the di-electric BDV of  insulating oils, both new and in - service from transformers,_ switchgear & other electrical equipments
   
  Function
Our instruments have advanced functions for fully automatic tests. They enable the operator to simply prepare oil test cell, load it with sample oil, place it in the chamber and initiate the test sequence. The test set carries out (if necessary unattended ), the series of tests as defined in the particulars test standard & on completion of a test sequence the average break down
voltage value is displayed & the value for each individual may be recalled.
   
"Initial wait time, rate of rise of test voltage, intermediate stir time, settling time & number of tests" are all pre - programmed into the sequence itself & kept the test program parameters stored in memory.
   
When Mains will be Switched ON the instrument will get ready.
   
Once the instrument is ready, press H. V. ON button to conduct the test as per the pre-programmed settings.
all the number of tests will be conducted one after another automatically.
   
Instrument will note the breakdown voltages, calculate average BDV & display. A Test report can be printed on the printer
by. pressing PRINT button.
   
The instrument will save individual BDV & average of last three test samples.
