Is Electrisim a good EasyPower alternative?

For arc flash, short circuit, motor starting and load flow, yes, on any operating system. If you depend on printed arc-flash labels or large device libraries for coordination, keep EasyPower for those tasks.

Does Electrisim do arc flash like EasyPower?

Yes: IEEE 1584-2018 arcing current, incident energy, arc-flash boundary and an NFPA 70E-style PPE category at each bus, from a maximum three-phase IEC 60909 short circuit. Results appear on the diagram; label printing is not built in. See the arc flash documentation.

Does Electrisim support ANSI/IEEE C37 short circuit?

Yes, in beta, next to IEC 60909. Tick the standard on the Pandapower tab of the Short Circuit dialog. See the short circuit documentation.

Does Electrisim run on a Mac?

Yes. The cloud app runs in any modern browser on macOS, Windows or Linux, with nothing to install.

How much does Electrisim cost compared to EasyPower?

$10 per month for Personal or $40 per user per month for Company, with arc flash, short circuit, coordination and motor starting included. No installation or licence server. See pricing.

Choose the engine per study — pandapower, OpenDSS, or ANDES. Full documentation →

Arc flash — IEEE 1584-2018 incident energy, arc-flash boundary and PPE category on every bus
Short circuit — ANSI/IEEE C37 (beta) and IEC 60909, with a dashboard and PDF report
Protection coordination — fuse melt and relay trip times, TCC curves and miscoordination warnings (beta)
Motor starting — voltage dip for DOL, soft-start, star-delta, autotransformer and reactor starting
Load flow — voltages, loading and losses, with the Network Health Dashboard
Harmonics — voltage and current THD with OpenDSS
Transient stability — rotor angles after faults with ANDES, included in every plan
Import — pandapower (.py) and OpenDSS (.dss) files become a single-line diagram

Validated against commercial software

Results are driven by mature open engines and checked against commercial tools and independent academic work.

Commercial-tool validation

pandapower power flow and short-circuit results are validated against DIgSILENT PowerFactory and PSS Sincal with strict tolerances — continuous CI on every change.

When Electrisim is the right EasyPower alternative

Best fit for

Facility and plant engineers who update short-circuit and arc-flash results when the network changes
Consultants running arc flash, short circuit and motor starting on smaller sites
Engineers on macOS or Linux, or teams that would rather not install software
Students learning arc flash and protection on open engines

Still use EasyPower when you need

Arc-flash labels and field documents printed from the study
Large manufacturer device libraries for coordination
Existing EasyPower projects and client deliverables
Client requirements that name EasyPower

You can run day-to-day studies in Electrisim and keep an EasyPower seat for label printing or where a contract requires it.
