How to take of Transformer oil Break down voltage test?..

Answer / pillay

i assume your question is how to take transformer oil for
breakdown voltage test.
the sample is taken from the oil drain cork. the containers
and any other equipment used for this job must be ensured it
is dry and not contaminated or this contamination will
influence the oil test results.
1. The sample is connected from the drain cork through a
small hose to a syringe. the initial oil is not taken. from
the syringe the oil is transfered to a sample bottle slowly
without forming air bubbles or too much external atmospheric
contact.this oil is used to test for the dielectic breakdown
voltage in a special tester.the minimum breakdown voltage
depends on the operating systems voltage and local
regulations.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
