Is your testing team equipped for critical df/dt numerical protection relay testing? At Myriad Industrial Solutions LLP in Mumbai, we understand that rate-of-change-of-frequency (df/dt protection) testing demands extreme precision during grid disturbances. The CROXS CRA 160LHi-A Three Phase Relay Test Set is built exactly for this purpose. Operating on pure AC mains (100–240V) with no batteries to maintain, this high-performance kit features an extended 4×300V voltage range and 6×20A/3×40A current outputs. It allows protection engineers to flawlessly execute manual ramps, automatic test sequences, and frequency shifting to verify pick-up thresholds and operating times for df/dt relays. Engineered for Indian DISCOMs, TRANSCOMs, GENCOMs, EPC projects, and substation commissioning in PAN India, it provides a rugged, cost-effective testing alternative. 👉 Discover our full testing range, download technical data sheets, or request an official instrument quotation directly at ElectricalTestKit.com today!
