To run full simulations on all types of relay schemes, microprocessor, electromechanical, or a mixture, you need an instrument that can generate high test power and provide flexible configurations for many types of tests.
The Doble F6150, with its high power rating and built-in configuration flexibility, is the industry's only true single-box solution for simulation testing of all relay protection schemes. With the Doble F6150, you can easily run a variety of tests to determine whether your relays are detecting signals properly, communicating correctly, and responding appropriately to power system events. In addition, with its high-accuracy output, the Doble F6150 can be easily applied to calibration testing of transducer and energy metering applications, including meters rated at 0.2 Class.
Even tests that are difficult to perform with other instruments are simple with the Doble F6150.
• Ground overcurrent relays are typically difficult to test, due to low tap settings and high burden. Using multiple current ranges, the Doble F6150 delivers high power at low current to meet this challenge.
• Relay schemes such as overcurrent and distance protection require testing at 20 to 30 times the nominal secondary current value. The Doble F6150 delivers 180 A at 675 VA to meet virtually all high-current test requirements.
