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 ...

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 ...

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 ...

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 ...
