Description
CircuitSim is a comprehensive SPICE circuit simulation tool featuring a library of over 3,000 components and a contemporary schematic editor, all accessible online for free without the need for installation. Designed for use by students, educators, and professionals alike, it operates directly in a web browser, making it compatible with Chromebooks and secured school laptops without requiring administrative access. Users can perform seven types of analyses, including interactive and transient analyses, with results displayed on oscilloscope-style graphs and the ability to place probes at any point in the circuit. Additionally, users can create custom components from SPICE model text or import symbols from KiCad, enriching the simulation experience. CircuitSim also supports the import of Multisim Live designs before its scheduled retirement on September 15, 2026, making it a unique browser-based solution that can handle .csim, .ms14, and .msjs files, preserving wiring, component placement, net labels, probes, and simulation configurations. Furthermore, classroom licensing options are available, providing features such as seat assignments, anonymous student seating, and private student project spaces to enhance the educational experience. This ensures that educators can effectively manage their classroom environments while leveraging advanced simulation tools.
Description
Relay Tripping Curves PRO2 (RTC2) is a Windows-based application developed by protection engineers specifically for their peers in the field. It enables users to plot trip curves for relays, circuit breakers, and transformers on a log-log graph, ensuring the selectivity between different devices is verified, while also producing comprehensive technical reports necessary for professional engineering tasks.
Field testing equipment may provide measurements, but they often fail to contextualize these readings with the primary system, visualize the curves, or document that settings are indeed coordinating, a gap that RTC2 effectively addresses.
Key features include support for seven relay manufacturers, each replicating the original display and terminology, ten circuit breaker trip units encompassing L/S/I/G zones, and a transformer damage curve compliant with ANSI/IEEE C57.109-2018 standards, as well as capabilities for inrush and short-circuit current analysis, ΔT selectivity calculations among devices, and the generation of PDF reports that feature primary-equivalent current, curve equations, plots, and signatures. Moreover, the software is fully bilingual in English and Spanish, and it operates entirely offline.
Users can explore a free DEMO version that has no time restrictions, while paid editions offer a perpetual license for a one-time payment. This flexibility ensures that all engineers can find a suitable option tailored to their needs.
