The short circuit test by hipot is test of any electrical device will produce of leakage current due to the voltages and internal capacitance present within the product. Yet due to design flaws or other factors, the insulation in a product can break down, resulting in excessive leakage current flow. This failure condition can cause shock or death to anyone that comes into contact with the faulty product which this project will change computer to controller for easy to test, precise and more secure
