We will introduce a 2D electric field analysis assuming the section between transmission towers using our "PHOTO-VOLTjω." Above the power lines, there are two overhead ground wires. Below is the ground, which is also set to 0V. The analysis results are displayed as complex numbers. The analysis is conducted using the finite element method. 【Case Overview】 ■ Analysis Target: Power lines, ground, and surrounding space ■ Analysis Software Used: PHOTO-VOLTjω ■ Voltage Condition: Each conductor's voltage is 500kV/√3 ■ Analysis Type: 2D electric field analysis *For more details, please download the PDF or feel free to contact us.

The wound-type capacitor has a structure that alternately layers electrode foil and dielectric, featuring a compact design while increasing the surface area of the electrodes. In "PHOTO-VOLTBM," there is no need for air mesh, allowing for the easy creation of complex-shaped models in conjunction with programmatic mesh deformation. In this case study, we will conduct an electric field analysis of the wound-type capacitor. Additionally, we will compare the capacitance obtained from the analysis with the theoretical value.

There is a capacitive proximity switch that can detect both metal and non-metal objects without contact. This sensor detects objects by converting changes in capacitance into electrical signals. In this case study, we will analyze the capacitance between a grounded detection object (metal) and the electrodes within the sensor. We will also observe the changes in capacitance when the relative position of the electrodes is altered from the perspective of the detection object. 【Case Overview】 ■Software Used: PHOTO-VOLT or VOLTjω ■Analysis Type: 3D Electric Field Analysis *For more details, please refer to the related links or feel free to contact us.

Here is an example of nonlinear electric field analysis of cable joints. The electric field analysis software "PHOTO-VOLT" and "VOLTjω" can be selected from two modes: electric field analysis and current distribution analysis. This case uses current distribution analysis. In the electrical insulation design of joints for DC power cables, it is necessary to consider the nonlinear conductivity characteristics of the insulator.

Here is an example of electric field analysis for a comb-type electrostatic actuator. Electrostatic actuators generate electrostatic force based on the sign of the charges present on opposing electrodes, so electric field analysis is applied. In "PHOTO-VOLT," it is possible to calculate the potential distribution, electric field distribution, and the electrostatic force acting on the electrodes. Additionally, we consider whether the order of the electrostatic force obtained from the analysis results is reasonable.

When a high voltage is applied to a coil, as in the case of surge voltage, a locally high electric field is generated, leading to discharge and damage to the coil's insulation. In this case, we analyze the electric field generated when a voltage is applied between insulated coil wires (cables). The electric field strength generated per 1[V] of voltage between the coil wires can be multiplied by the magnitude of the actual applied voltage to consider it as the maximum electric field strength. Please feel free to consult us regarding any concerns about electromagnetic field analysis. 【Case Overview】 ■ Software Used: PHOTO-VOLT *For more details, please refer to the related links or feel free to contact us.

In this analysis case, we will introduce a comparison between the calculated values of the capacitance of a cylindrical capacitor and the theoretical solutions. We will analyze three conditions: "Cylindrical Capacitor (Air)", "Cylindrical Capacitor (Dielectric - Radial Two Layers)", and "Cylindrical Capacitor (Dielectric - Circumferential Two Layers)". Since this case involves electrostatic field analysis, it can be analyzed not only in VOLT but also in VOLTjω.

The analysis of capacitance is shown below with shape data created from planar elements for the outer surfaces of each component. The number of nodes is 1112, and the number of elements is 1064. Since the boundary element method is used, a mesh for air is not required. The analysis calculations were performed using the electric field analysis software PHOTO-VOLTBM.

We analyzed the electric field distribution between the anode and cathode when 1V and -1V were applied, respectively, in a vacuum. It is assumed that the potential does not vary with time. The analysis module used is PHOTO-VOLT. Since the electrodes are conductors, the moment the potential is applied, charges move to the surface of the electrodes. Therefore, the potential is set on the electrode surface, and modeling the interior of the electrodes is no longer necessary. (Only the space in the vacuum is modeled.)

The "PHOTO series" offers analysis solvers that utilize the most suitable simulation methods for a wide range of target fields, from high-frequency electromagnetic waves to low-frequency electric and magnetic fields, based on the analysis theme. Unlike other commercial software packages that handle all phenomena with a single analysis solver, we use the most appropriate analysis solver for the purpose, ensuring high analysis accuracy and detailed responsiveness to needs. Additionally, you can select only the necessary modules suited to the problem, which helps keep the implementation costs economical. It is also easy to expand functionality by adding modules, and by combining them, it is possible to handle coupled analyses such as heat generation due to eddy currents and stresses or deformations caused by electromagnetic forces. All products are compatible with three-dimensional problems, and the transient response analysis module can handle nonlinear materials.
