Study of Temporary Overvoltages in 110/13.8/6.6 Kv Power Substation

International Journal of Advance Research and Innovation, 2017
Over voltages, be it of any magnitude, shape or amplitude adversely affect the smooth working of power substation and may prove to be fatal in many cases. In this paper study of insulation coordination of temporary over voltages (TOV) has been carried out in 110/13.8/6.6 kV substations.

Transient Stability Analysis of Wind‐Thermal Bundled Systems Under Sequential Filter Removal

Engineering Reports, Volume 7, Issue 6, June 2025.
This paper proposes a coordinated control strategy for wind and thermal unit scheduling under filter ordered removal based on the principle that retaining part of the filter can enhance system stability. By establishing a grid architecture model, introducing static stability constraints, transient stability constraints, and filter capacity constraints,

Effect of intermittent cathodic protection on potential and corrosion rate of carbon steel in soil simulating solution [PDF]

, 2017
Carbon steel in aerated soil operates in cathodic protection (CP) condition if the IR-free potential is more negative than –0.850 V CSE, which corresponds to a corrosion rate lower than 0.01 mm·a-1.

Transition‐Metal Dependence of Anion Redox Reversibility in Amorphous Electrodes

ChemElectroChem, Volume 12, Issue 8, April 14, 2025.
One major problem in anion redox, which is expected to contribute to the higher capacity of energy storage batteries, is the low reversibility owing to the phase separation of the anion component. The validity of transition‐metal selection guidelines for reversible anion redox reactions has been demonstrated, even for amorphous materials with ...

An open‐source LED lamp for use with the LI‐6800 photosynthesis system

Applications in Plant Sciences, Volume 13, Issue 1, January-February 2025.
Abstract Premise Controlling light flux density during carbon dioxide assimilation measurements is essential in photosynthesis research. Commercial lamps are expensive and are based on monochromatic light‐emitting diodes (LEDs), which deviate significantly in their spectral distribution compared to sunlight.
