The Quasar-C is a powerful relay test set and secondary injection test set designed for protection relay testing applications where full current output capability is essential.
It includes the same three dedicated current outputs as the standard Quasar, without voltage outputs as standard. When voltage testing capability is required, the Quasar-C can be upgraded to Quasar-C+ with a configurable V4 voltage module, or to full Quasar with the standard four-output voltage amplifier module.
Looking for a powerful relay test set focused on current injection, protection relay testing, secondary injection testing, IEC 61850 applications, and GOOSE-based digital substation schemes? The Quasar-C Smart Relay Tester is designed for professionals who need the full dedicated current output capability of the Quasar platform, without voltage outputs as standard.
The Quasar-C relay tester includes the same three dedicated current outputs as the standard Quasar, making it an excellent solution for overcurrent, differential, earth fault, breaker failure, and other current-based protection relay testing applications.
As part of the modular Quasar platform, the Quasar-C can be upgraded at any time to a Quasar-C+ or to a full Quasar configuration by adding the appropriate voltage amplifier module.
 
 
Why Choose the Quasar-C Relay Tester?
Full Quasar Current Output Capability: The Quasar-C includes the same three dedicated current outputs as the standard Quasar, providing powerful current injection for protection relay testing.
Current-Only Configuration: Designed for users who need high-performance current injection but do not require voltage outputs as standard.
Secondary Injection Test Set for Current-Based Protection: Ideal for overcurrent, differential, earth fault, breaker failure, and other protection functions where accurate current injection is essential.
Upgradeable to Quasar-C+: The Quasar-C can be upgraded by adding a configurable V4 voltage module, providing one flexible voltage output channel.
Upgradeable to Full Quasar: The Quasar-C can also be upgraded to a standard Quasar configuration by adding the four-output voltage amplifier module.
Scalable Investment: Start with a current-focused relay test set and expand the equipment later when voltage testing capability is required.
IEC 61850 and GOOSE Testing: The Quasar-C supports IEC 61850 and GOOSE-based testing, making it suitable for modern digital substations and communication-based protection schemes.
Relay Testing Software: The Quasar-C works with intuitive relay testing software for manual, automated, and preconfigured tests, helping users reduce testing time and improve repeatability.
Multiple Connection Modes: Integral Wi-Fi, Ethernet LAN, dedicated IEC 61850 port, and expansion port provide flexible connection options for field, substation, and laboratory environments.
Rugged and Portable Design: Built for field use, the Quasar-C is designed for professionals who need reliable relay testing equipment in demanding environments.
