According to Grossi, electronics used in one of four experiments aboard the satellite was hit by an overvoltage just before the break, damaging some circuitry.
32.
They will also include high energy overvoltage MOV ( Metal Oxide Varistor ) protection, and circuit over-current protection in the form of a Polyswitch.
33.
The two brass hex-head objects on the left cover the suppressors, which act to short overvoltage on the tip or ring lines to ground.
34.
Thus, a crowbar will not automatically return to normal operation when the overvoltage condition is removed; power must be removed entirely to stop its conduction.
35.
These fast overvoltage spikes are present on all distribution networks and can be caused by either internal or external events, such as lightning or motor arcing.
36.
The AC output will be maintained during an AC mains overvoltage condition as the Rectiverter runs in inverter mode supplying energy to the load from the batteries.
37.
The level of energy in a transient overvoltage can be equated to energy measured in joules or related to electric current when devices are rated for various applications.
38.
Computer power supplies may have short circuit protection, overpower ( overload ) protection, overvoltage protection, undervoltage protection, overcurrent protection, and over temperature protection.
39.
Even when exposed to large overvoltage surges, these safety-rated capacitors must fail in a fail-safe manner that will not endanger personnel or property.
40.
In the worst case, reactive elements can interact with the system and with each other to create resonant conditions, resulting in system instability and severe overvoltage fluctuations.
