Answer / zan

KW


A Switched-mode power supply (also Switching-mode power
supply, SMPS, or simply Switcher) is an electronic Power
Supply Unit (PSU) that incorporates a switching regulator
in order to provide the required output voltage. An SMPS is
actually a power converter that transmits power from a
source (e.g., a battery or the electrical power grid) to a
load (e.g., a personal computer) with ideally no losses.
The function of the converter is to provide a reliable
output voltage often at a different level than the input
voltage.

What should be the voltage between Neutral and Ground in secondary side of the step down transformer (230 V to 110 V) with no load condition?

0 Answers   Jindal,

We have 11kV/110V three phase indoor potential transformer in 66/11kV Sub-station, where the failure of PT is frequently happening and the rating of the PT is 0.2 class accuracy, with primary star and seconday (two cores) star connected. Some experts has suggested to not to connect the PT Primary neutral to the ground because when transformer neutal NCT connection is loose; the faulty current will flow through the PT primary neutral, resulting into failure of PT. My question is: Is it necessary to remove the primary neutral connection of the PT from ground? if not, what would be the reason for failure of PT. Please guide me.
