  • Testing Cables with High Voltage - Cirris Systems Corp.

    2 days agoTo hipot test a net, you connect all of the contacts in the net to high voltage and connect all other contacts in the device to ground. For example, if you have a wire that connects two pins, the high voltage will be simultaneously apply to both of those pins and the entire wire will be raised in voltage.What Kinds of High Voltage Tests Are there?There are three common high voltage tests. 1. Dielectric Breakdown Test 2. Dielectric Withstanding Test 3. Insulation Resistance TestWhat Is Dielectric Breakdown Testing?Dielectric breakdown testing answers the question, How much voltage can I apply between the wires before the insulation fails? The test increases...What Is Dielectric Withstand Testing (Dw)?Dielectric withstand testing answers the question, Will this cable withstand a required voltage for a required time? The test applies the require...What Is Insulation Resistance Testing (IR)?Insulation resistance testing tries to answer the question, Is the resistance of the insulation high enough? The test applies a voltage and measu...How Do These Hipot Tests Affect Quality?All of these tests are tools used to understand how a cable will perform and to monitor any changes in the cables performance.Dielectric Breakdown...With All The High Voltage Being Used, What About Safety?Products being designed today should comply with product safety regulations. Some of these regulations reduce the chance of receiving harmful elect...Where Is The High Voltage applied?To understand how hipot testing works youll need to understand where to connect the high voltage supply. Hipot testers usually connect one side of...What Causes Current to Flow Through An insulator?Insulation does not conduct. But if you use enough voltage even the best of insulations will allow some current to flow. There are several reason...Which Cirris Testers Are Capable of High Voltage Testing?Cirris manufactures industry-leading high voltage cable testers.
