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 ...

The constant availability of medium- and high-voltage electrical assets used in power generation, transmission and distribution is important for a reliable power supply at both utilities and ...

BAUR Prüf-und Messtechnik GmbH has introduced “liona” - a portable device for measuring and locating partial discharge s during operation (online). With this device, medium- and high-voltage cables ...

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 ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

Weichai Power has developed a spark plug heat rating measurement method and system using spark discharge current for precise evaluation. By controlling discharge current and measuring temperature ...
