    Water use in nuclear & coal-fired power generation

    Dear Colleagues: Could somebody give me some ballpark figures about water use in large nuclear & coal-fired power generation plants. Are there any benchmark figures, such as tonnes of water use per GW and hour of operation? What temperature increase can be expected in water temperature between...

    What is the difference between a voltage regulator and a Dynamic Voltage Restorer (DVR)?

    Both are used to mitigate the effects of voltage dips. Dips are characterised by the depth - the retained voltage - and the duration. Short and deep dips are best served by a DVR while long and shallow dips are the province of the voltage regulator. A voltage regulator has no energy store...

    My system suffers from voltage dips that appear to originate outside my installation. What can be done to resolve the issue?

    The correct way to proceed is via the Distribution Network Operator (DNO). It is the responsibility of the DNO to ensure that no consumer causes interference to another. Of course - every consumer affects and is affected by all other local consumers to some extent, so whether the interference is...

    My process control system is not reliable and I suspect a voltage dip problem. Where do I start?

    The steps in identifying the problem are: Monitor at the supply to one or more of the affected devices. One problem is that the monitor threshold settings need to be set carefully so that all interesting events are captured, but the smaller, uninteresting events are not. This can take some...
