Download this article in PDF format. 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 ...

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 ...

Weir flow measurement is a fundamental hydraulic technique used to estimate channel discharge by relating the upstream water level (stage) to the flow rate. The stage-discharge relationship, central ...

“Lightweight, compact, powerful and easy to handle” were the criteria when the engineering team of BAUR GmbH were developing the new device - PD-TaD60 - for partial discharge measurement and location.

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 ...

For more than 50 years, companies have performed partial discharge (PD) testing on electrical assets as part of ongoing predictive maintenance programs. Data obtained through PD testing and monitoring ...

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 ...

Batteries serve as the main source of power in a substation in the event of an AC outage. They power critical loads and equipment like relays, indicator lamps, circuit-breaker controls, motor ...

OMICRON’s MPD 800 universal partial discharge (PD) measurement and analysis system represents the next generation of the company’s innovative MPD PD testing technology, which is based on 20 years of ...
