The proper operation of the protective relays is critical in the reliability and safety of power systems, protecting other devices from damage and helping to the system security. Accordingly, the testing of relays is required during the installation and commissioning process, and as part of the maintenance programs throughout its service life.
Protection testing. Protection systems play a key role for the safe and reliable operation of today’s electricity power systems. Properly working protection devices help to maintain the safety of the system and to safeguard assets from damage. In order to ensure reliable operation, protective relays as well as recloser controls must be tested throughout their life-cycle, from their initial development through
Protection systems play a key role for the safe and reliable operation of today’s electricity power systems. Properly working protection devices help to maintain the safety of the system and to safeguard assets from damage. In order to ensure reliable operation, protective relays as well as recloser controls must be tested throughout their life-cycle, from their initial development through production and commissioning to periodical maintenance during operation.
Our test equipment is ideal for each of these life-cycle phases and for any environment. As a reliable long-term partner, we offer state-of-the-art testing solutions which are continuously being developed and maintained to help you to keep pace with the increasingly complex requirements of your systems.
Relays testing may range from a simple check of some points of the relay characteristic to a complete verification of the protection scheme logic, even including the response to transient waveforms, harmonics, etc

TEST-630 is designed with fuse on the mains supply and electronic protection for overload on the current (open circuit) or voltage outputs(short circuit), with immediate isolation of the output and alarm indication. Also diagnostic message for the setting of wrong data, mistakes on the input etc. There's also electronic protection in case of counter-feed of voltage output, if any incorrectness happen, the alarm light shall flash. And Overheat LED indicator shall flash for Protection against over-temperature, on all outputs.Universal testing system TEST-630 (6×35A, 6×300V) can test all types of protective relays, including modern IEC61850 based relays. Other test works, such as transducer, energy meter, indication meter, etc., can also be done easily. It's the ideal test
