Looking for a flexible and accurate relay test set for protection relay testing, secondary injection testing, and IEC 61850 applications? The Quasar-V Smart Relay Tester is a scalable secondary injection test set designed for utilities, industrial facilities, maintenance companies, commissioning teams, and relay manufacturers that need reliable relay testing equipment with advanced digital substation capabilities.
The Quasar-V relay tester combines integrated voltage amplifiers, convertible voltage outputs, IEC 61850 testing capability, GOOSE messaging support, and modular expandability. It is ideal for users who require a professional three-phase relay test set today, with the option to upgrade to a full Quasar configuration whenever dedicated current amplifiers are needed.
 
The Quasar-V is an industrial-grade secondary injection test set designed for testing protection relays in substations, industrial power systems, and digital protection schemes. It supports a wide range of protection relay testing applications, including overcurrent, distance, differential, voltage, frequency, and IEC 61850-based protection functions.
The Quasar-V includes integrated voltage amplifiers and 4 x 300 V voltage outputs. As in the Quasar platform, these voltage outputs can be converted into current outputs, allowing flexible configurations such as 4 x 5 A or 3 x 5 A + 1 x 300 Vdc. This makes the Quasar-V a versatile relay tester for many routine maintenance, commissioning, and troubleshooting tasks.
Unlike the standard Quasar configuration, the Quasar-V does not include dedicated current amplifiers as standard. However, it can be upgraded to a full Quasar relay test set by adding the standard plug-and-play current amplifier module with three current outputs. This module can be purchased separately and installed at any time, allowing users to expand the system as their relay testing requirements grow.
