the GND voltage of the neutral wire on the AC output side is found to be 67 V. Test the inverters in other offices that are connected in the same way, and find that the GND voltages of the neutral wires on the AC output side
a后者仅限于局部安装条件使得正常状态下中性线上的电压不超过特低电压时。 The latter is only restricted in partial installs the condition to cause under the normal state in the neutral axis voltage not to surpass time the special low voltage.[translate]...

In a 3-phase circuit, if we measure the voltage between any of one phase from the 3-phase and neutral point then it is known as line-to-ground voltage. Similarly, if we measure the voltage between any two phases from 3-phase then it is known as line-to-line voltage. ...
The presence of an effectively grounded overhead shield wire or neutral on the line will reduce insulator voltages by 30%–40%, depending on the line configuration. • Line surgearrestersinstalled every few spans can improve induced flashover performance for distribution voltage lines (spacing line...
Low voltage electrical protection system when faced with faults due to the loss of electrical continuity of the neutral wire between the transformation centre and the specific lead-in cable.The system composes an electronic device (X2) with two terminals, characterised in that it presents low ...
This paper introduces an optimized DC–DC converter that employs a modified switched inductor-capacitor technique to achieve ultra-high voltage gain for renewable energy systems. The development is based on adding one cell of modified switched inductor (
Y-connection advantages: for high voltage windings, the most economical; can have neutral points available; allow direct ground or by impedance ground; allows reducing the insulation level of neutral point (grade insulation); on each phase neutral point is set at the tap, tap-changer you can ...
In order to study the permanent magnet generator system, the mathematical model of the permanent magnet generator in the synchronous rotation orthogonal coordinate system is established. Constant phase amplitude transformation is adopted in this paper. Since the neutral point of the star network three-...
