Partial discharge (PD) measurement has been used for several decades to assess the condition of high voltage (HV) and medium voltage (MV) electrical apparatus. In the past, the application was mostly ...

Power cables are important assets in electric utility transmission networks for the reliable operation of power systems. To prevent catastrophic failures in underground cables and terminations, it is ...

Lithium-ion cells gradually discharge even when they are not connected to anything. Some self-discharge is normal. However, excess self-discharge indicates potentially catastrophic problems within the ...

High-voltage dc cable is a core technology for long-distance power transmission and has made it possible to interconnect power systems over long distances between countries and land masses separated ...

One characteristic of lithium-ion cells is a phenomenon called self-discharge. The concept of self-discharge is simple: Take a cell, charge it up, measure its open-circuit voltage (OCV), and let it ...

The OCV of the cell is determined by the cell’s state-of-charge (SoC). However, the temperature of the cell is another important factor, as the cell’s OCV will vary with temperature. This effect is ...
