CROXS CRA160LSi-A Numerical Relay Test Set AC Mains Operated, 6-Phase Universal Protection Relay Testing Kit

The CROXS CRA160LSi-A is an AC mains-operated relay test set built for testing numerical and static protection relays used across Indian DISCOM, solar power plant commissioning, power transmission and generation companies, EPCs and testing & commissioning applications. As a 6-phase current + 6-phase voltage universal test set, it supports single-phase, three-phase, and multiphase relay testing without needing battery backup, making it ideal for panel rooms and substations with a reliable AC supply.

The CRA160LSi-A is a complete commissioning and maintenance tool for protection engineers, generating precise current and voltage signals up to [20 A / 130 V] per channel, enabling accurate testing of overcurrent, earth fault, distance, differential, and directional protection relays. Its numerical relay test capability makes it suitable for modern digital substations having numerical relays, while remaining compatible with legacy static relay testing requirements.

Key applications include relay commissioning, protection scheme validation, periodic maintenance testing, and relay panel testing for utilities, EPC contractors, and independent testing agencies. The unit supports manual, ramp, and shot testing modes, along with automated test sequences for faster, repeatable results in the field.

Backed by CROXS Instruments' authorised Indian distribution through Myriad Industrial Solutions LLP, the CRA160LSi-A offers a reliable, cost-effective alternative to iother mported relay test sets for India's growing numerical relay testing needs with local sales, technical support, and after-sales service.
