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.

Description

ZapSketch is an online tool designed specifically for electricians, electrical contractors, and estimators to facilitate the planning of electrical home runs. It allows users to import floor-plan PDFs, draw walls on a blank canvas, or start from a quick sketch, enabling them to place panels, junction boxes, and devices while routing circuits and raceways efficiently. As users modify their layouts, the application automatically measures run lengths and offers insights on preliminary conductor sizing, ampacity, voltage drop, and conduit fill based on the NEC 2023 standards. Users can also access circuit schedules and export their marked-up plan PDFs along with raceway pull schedules for purposes such as estimating, review, and transitioning to the field; however, some export options and unmarked reports necessitate a Pro subscription. Additionally, there are free standalone calculators available for voltage drop, wire sizing, and conduit fill. While ZapSketch serves as a valuable preliminary planning tool, it is essential to note that it should not replace thorough code reviews, engineering judgment, or the verification of actual project conditions. This tool enhances workflow efficiency and supports better project management for electrical professionals.

Pricing Details

$19/month
Free includes the planning workflow and preliminary checks; PDF exports are watermarked and redact commercial pull and calculation details. Pro is $19 per month, or $190 per year, and adds unwatermarked PDF exports, full raceway pull schedules, complete preliminary calculation reports, and commercial-use output. Standalone voltage-drop, conduit-fill, and wire-size calculators are available without signup.
