Doble's Single Phase Relay Test Sets

Posted by Protec Tech Team on

Doble F2253 Single Phase Relay Test SetRelays play a critical role in the protection of electrical power systems. They are used to monitor and control the operation of power system components.  For example, if a protective relay were to senses a fault condition, it could tell a circuit breaker or some other protective device to open and thereby isolate the faulted portion of the circuit.  

Over time, relay contacts and other components, undergo physical and electrical stresses which should be addressed in a regular testing and maintenance program.  However, these are not the only reasons to perform relay testing.  Electrical systems sometimes change as they grow and are updated.  Such changes could require adjustments to the relay settings and area of protection. Once these changes have been implemented, they must then be verified to have had the intended impact on the protective characteristics of the relay. They are essentially the brains of the protective system.  If the relay fails to operate as intended, then the protections portion of the system could prove ineffective and potentially diminish the overall reliability of the power system.  Regular testing and maintenance is a preventive measure used to mitigate the costly impacts associated with being unprepared to react when fault conditions occur.

Doble Test Equipment offers a variety of relay test equipment to cater to most testing needs. These diagnostic tools can help identify problems that could contribute to the mis-operation of a protective relay. The proactive identification of such conditions will aid in the protection of the power system components and prevent unexpected service interruption.

Below are some of the popular Doble models of relay testers.

Doble F2253 Single Phase Relay Test Set

The F2253 is a single phase relay test set capable of producing in service conditions of both normal and faulted parameters to verify the response of the protective device. The F2253 has a modular design that lets you add current amplifiers to extend the range of applications and satisfy the testing requirement when testing higher burden relays..

Key Features

  • 1 voltage source and 3 (150 VA) active source current amplifiers
  • Optional modules let you increase power output
  • Six-digit multimode timer
  • 2 logic and signal inputs
  • 2 independent logic outputs that lets you simulate carrier, circuit breaker and scheme logic
  • ProTesT software lets you run dynamic-state simulation tests, assess protection schemes and analyze results
  • Lets you run transient tests using EMTP and DFR playback or recorded faults.
  • User-friendly control panel
  • Built-in GPS system lets you conduct end-to-end power simulations
  • Automated range setting feature
