Transformer Winding Resistance& On-Load Tap….
The main causes of transformer winding deformation are.
Negative voltage is derived from the same transformer winding.
HZ-3320D 3 channels transformer winding resistance measurement meter 20A I.
The purpose of measuring the DC resistance of a transformer winding[Aug 21, 2019].
The DC resistance of the transformer winding is measured by voltage drop method or bridge method.
The safe operation andservice life of dry-type transformers depend to a large extent on the safety and reliability of the transformer winding insulation.
(3) The dead zone orthe malfunction of the protection system causes the transformer winding to withstand the short-circuit current for too long.
When the dry-type transformer winding temperature continues to rise, if it reaches 155 °C, the system outputs an over-temperature alarm signal;
(1) Measure the insulation resistance of the transformer winding and the final screen;
Transformer winding DC resistance test is a transformer in the transfer, overhaul and change the essential experimental projects tap.
Therefore, the frequency response method is to determine the degree of transformer winding deformation through the response curve before and after the acquisition of the fault.
Additionally, the LinkSwitch-4 controller's primary-side regulated sensing methodology eliminates expensive and unreliable optocouplers,replacing them in the feedback loop with a simple transformer winding.
To meet the rapid measurement of the transformer winding resistance needs, our company used their technological advantage, developed this instrument.
Ratio changes involve a mechanical movement of a contact from one position to another, anda transformer tap changer test should also be undertaken during the transformer winding resistance test to validate proper operation.
This sound occurs when the high voltage of the transformer winding causes the outgoing lines to flash with each other or when they are flashed to the outer casing.
The AC power frequency withstand voltage test of the three-phase transformer does not have to be phase-separated, but the three-phase lead-out end of the same-side winding must be short-circuited before testing,otherwise the insulation of the transformer winding may be damaged.
Transformer winding between the inter-turn, inter-layer, inter-stage and inter-phase insulation of the vertical insulation induction voltage test, it is an important transformer insulation test items.
Most of the oil-immersed transformers are Class A insulation materials, and A-class insulation material temperature of 105 degrees Celsius,the requirements of the transformer winding temperature can not exceed 95 degrees Celsius, the upper oil temperature should be about 90 degrees Celsius;
(1) The transformer winding can not withstand the impact of various short-circuit faults encountered in its operation, especially the huge impact caused by the transformer outlet or short-distance short-circuit fault;
Transformer Winding Resistance& On-Load Tap Changer Test Set 1 Overview The DC resistance test of the transformer winding is the essential test item of the transformer after overhauling, overhauling and changing the tap changer.

Transformer winding deformation means that the size or shape of the winding changes irreversibly under the action of mechanical force or electric power, such as changes in axial and radial dimensions, body displacement, winding distortion, bulge, inter-turn short circuit, etc.
