Overview
  • Model DDA-1 Digital Data Acquisition Instrumentation and Control System
  • High-current output: 60,000 A for Model DDA-6000; 35,000 A for Model DDA-3000
  • Digital signal processing (DSP) technology
  • Variable pulse time and firing angle output current control
  • Compliant with NEMA AB-4 test guidelines
  • The DDA-3000 and DDA-6000 are designed specifically to test low-voltage power and molded-case circuit breakers equipped with thermal, magnetic or solid-state trip devices. The unique transformer and circuit design results in a very high-capacity test set in a very compact size. Advanced digital control and instrumentation provides exact testing capacity. The test sets can also be used for other high current applications, such as verifying the ratio of current transformers and performing heat runs or primary injection testing of high-voltage breakers and their associated protective relays.
  • Application
    Universal in application, the test sets will test virtually all low-voltage, molded-case and metal-clad, directacting ac circuit breakers produced by General Electric, Westinghouse, Federal Pacific, Square D, Gould, ABB, ITE, Siemens and other manufacturers. Model DDA-3000 is rated for testing breakers up to 3000 amperes. Model DDA-6000 is rated for testing breakers up to 6000 amperes. Rugged and reliable, Megger circuit breaker test sets will provide years of trouble-free operation. The test sets also may be used for other high-current applications, such as verifying the ratio of current transformers and performing heat runs or primary injection testing of high-voltage breakers and their associated protective relays. All Model DDA-3000 and DDA-6000 test sets have identical features, instrumentation and operational characteristics. The only changes in the specifications among the units are their size, weight and maximum output-current capacity.
