The Doble F6150 Relay Testing System is an instrument with flexibility and high power. It is used to run simulation tests on relays and protection schemes. It is a portable unit that can test everything from electromechanical earth faults to multifunction microprocessor protection schemes. It can perform various types of tests that include steady state tests, dynamic state tests, and stimulation tests.
The Doble F6150 can even be used for end-to-end protection schemes using GPS (Global Positioning System) to synchronize the remotely located 6150 device. This device has a high power rating with which one can test if the relays are getting proper signals. It can also check for communication errors and response time delays. They can also be used in calibration testing of transducers and metering applications.
