Compare LuzardoFax vs. Relay Tripping Curves PRO2

LuzardoFax serves as a HIPAA-compliant online fax solution tailored for medical practices, dental and mental health offices, physical therapy centers, law firms, insurance companies, and accounting firms throughout the U.S. and Canada. Every paid subscription includes a Business Associate Agreement that is signed digitally during the onboarding process, eliminating the need for email attachments or restrictions for larger tiers. Each signature is securely anchored to the Bitcoin blockchain with OpenTimestamps, ensuring independent verification of the agreement. Billing is straightforward and transparent, as LuzardoFax charges based on the actual number of document pages sent rather than by 60-second increments, preventing unexpected charges from dense documents or slow receivers. Additionally, failed fax attempts do not reduce your page allowance, and there is no risk of surprise overage costs since sending is paused at 110% usage instead of incurring extra fees. Security is prioritized with AES-256 encryption for data at rest, TLS encryption during transmission, comprehensive audit logs, and two-factor authentication for added protection. The service is available in both English and Spanish, offered on a month-to-month basis starting at $25, and prospective users can take advantage of a 14-day free trial to explore the features.

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.
