Measurement of insulation resistance on a power transformer. The purpose of the polarization index test is to ensure the equipment is operated or even feasible to do overvoltage test. Polarization index is the ratio of insulation resistance at the 10th minute by minute to 1 with a constant voltage.

All Electronics Electronic and Electro-Mechanical Parts and Supplies. 15V to 5V DC-DC Convertor. I was looking for a simple solution for pumping 1. I have designed various 1. 5v- 5V DC-DC Convertors by using special purpose chips. The problem was those chips are very difficult to obtain. Moreover, DC-DC Convertors are mostly required to use coil which is also difficult to get. The instruction is very simple, put 1. 5 Volt in your will get 5V at the output.
