Hi-pot decomposition

Hi-pot decomposition

Potentials that exceed the specifications of a battery should be avoided. Electrolyte decomposition or degradation of electrode materials can lead to reduced battery performance and lifetime. C rate. The term C rate describes how fast a battery is charged or discharged.

  • The Hi-pot Test - In Compliance Magazine

    Oct 15, 2014 · As the hi-pot voltage approaches the breakdown voltage, we see the inception of partial discharge in the solid insulation. Experts report that this inception of partial discharge is also the first step in the catastrophic dielectric breakdown of solid insulation.

  • Hi-pot Test Quality Control

    Aug 27, 2012 · There are 3 types of common Hi-pot test: Dielectric Breakdown Test – In this test, the voltage is increased until the dielectric fails or breaks down, in order to determine the highest voltage the cable can handle (also called the breakdown voltage). The dielectric is usually destroyed by this test, so this test is used on a random sample basis.

  • What does Hi-Pot mean? - Sunpower UK

    Hi pot test – Image Credit. Most of the safety standard bodies such as CSA and UL allow for the use of DC hi-pot voltages, and instead of 1500VAC the test uses 2121 VDC (√2 x 1500). At times, the voltage can be increased by 10% so as to reduce the test time from 1 minute to between 1 and 2 seconds.

It is also has more types of currents than some users realize. In its most basic form, an insulation resistance test is done with a hand-crank meter that measures megohms . An advanced tester plots megohms over a period of 10 minutes or more and displays voltage, leakage current, DAR, and PI ratios. Learn more about DAR and PI ratios. In an IR or megohm test the voltage applied and the total leakage current are measured between the windings and the motor frame/ground. Ohms law is applied to calculate the resistance in megohms. R=V/I Where R is resistance in megohms, V is voltage applied in Volts, and I is the total resulting current in micro Ampere (µA). A temperature correction factor is applied to correct the megohm measurement at present temperature to what it would be at a standard temperature. According to IEEE 43 and ANSI/EASA standards the standard temperature is 40°C. The leakage current of a used motor is often...
