What It Is

ElectricalSoft is an online calculation tool for low- and medium-voltage electrical installations. The page title clearly points to “Calculation of Low and Medium Voltage Installations.” Judging from the menu, it does more than individual calculations: it also includes project management, recent calculations, drag-and-drop single-line diagrams (SLD), databases, and documentation modules. Overall, it is positioned more like an electrical engineering design assistance platform.

Core Features and Ecosystem

Its feature coverage is fairly broad. On the low-voltage side, it includes I-P-V, LV circuits, installation systems, installation in conduits, capacitor banks, C/K factor, resonant frequency, and time-current curves. On the medium-voltage side, it covers technical specifications, earth fault current, CT/VT, transformer performance, and tap changers. For routing and installation, it provides modules for cable trays, conduits, short circuits, grounding conductors, and the Howe Method. The photovoltaic module offers a configurator, IV/PV curves, panel curves, inverter and panel comparisons, and built-in databases for inverters, panels, cables, and conduits. The captured text does not show any API, SDK, or third-party integration capabilities, so its ecosystem mainly consists of the built-in databases and documentation directory.

Pricing, Deployment, and Open Source Status

The page does not disclose specific pricing, subscription tiers, or payment methods. The terms state that the software project is maintained through voluntary user contributions, but that does not necessarily mean it is free or open source. The intellectual property clauses state that the software copyright and trademarks belong to the creator, and that users only receive usage rights under the terms. No open-source license, source code repository, or self-hosting instructions were found, so it should be treated as a closed-source online service or software without clearly stated licensing.

Pros and Cons

The main advantage is its comprehensive coverage of electrical calculation scenarios. In particular, it brings low voltage, medium voltage, photovoltaics, short circuits, grounding, cable routing/installation, and equipment databases into a single entry point, which can be valuable for engineers doing preliminary calculations and organizing reference data. The interface also offers layout options such as light/dark mode and RTL support. The downsides are also clear: the terms of service emphasize that it is provided “as is,” with no guarantee of accuracy, reliability, continuity, or fitness for purpose, and that it may be modified, suspended, or terminated at any time. Responsibility for engineering compliance rests entirely with the user. For formal design deliverables, it must be used together with local standards, manufacturer documentation, and manual review.

Who It’s For and Access from China

ElectricalSoft is suitable for electrical engineers, power distribution designers, and photovoltaic system designers for concept-stage calculations, learning, or cross-checking. It should not be used as the sole basis for issuing drawings without proper review. The captured text does not provide information on access from mainland China, so availability is unknown; payment methods are also not disclosed. If access, standards compatibility, or commercial support is limited, alternatives to compare include ETAP, DIgSILENT PowerFactory, EPLAN, Caneco BT, EasyPower, and OpenDSS.
