If the manager proposes to work within a cautionary zone, he must first assess the information he has to enable him to consider whether an inrush
may occur if no precautionary measures are taken.
In this paper, the result and the analyses of the water injection tests and some water inrush
cases in the coal mine are presented.
Mr Taylor said: "Mr Rees asked if he had in place a Precaution Against Inrush
scheme and he said he had and he was asked if he'd contacted the Mines Inspectorate and he said he had.
It is well-known that the inrush
currents are highly unbalanced among three phases.
event suddenly took place with water discharge of some cubic metres.
4) for switching unloaded transformer on gird (where inrush
current is been recorded) and breaking of loaded transformer (where switch voltage is been recorded) consists of generator (60 MVA), generator transformer (Tr 1, 50 MVA), bus (110 kV) and tested transformer (Tr 2, 50 MVA) with consumers on LV 10,5 kV side.
The converters have an efficiency of up to 78% and a working temperature range between -40[degrees] and 185[degrees]F and are equipped with over-voltage and over-temperature protection, as well as reverse polarity protection with inrush
TWO nights of temperatures down to -6, coupled with an inrush
of snow melt, again depressed weights in the JB Angling series on Loch Ken.
Last night UK Coal insisted that safety was the paramount consideration in the decision to close the mine, saying that continuing to cut coal in the flood-affected area would run the risk of a much more serious inrush
of water and potentially tragic consequences.
A power-up sequencing feature avoids branch circuit overload due to inrush
current on powering up the SPC appliance.
of foreign funds has made Japan the best performer of the major countries in dollar terms for the calendar year to date, but it still lags behind others in terms of a 12-month performance, according to the Dow Jones dollar-denominated country indexes.
The researchers suggest that the abnormal inrush
of potassium disrupts the heart's typical rhythm, leading to atrial fibrillation.
