MEGGER DDA-3000 AND DDA-6000 UNIVERSAL CIRCUIT BREAKER TEST SETS
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.
MEGGER DDA-3000 AND DDA-6000 UNIVERSAL CIRCUIT BREAKER TEST SETS specifications:
- Input
- ABecause Model DDA-3000/-6000 is used all over the world to test low-voltage circuit breakers, there are a number of test sets designed to contend with the many different input voltages and frequencies.When ordering, select the test set which best suits the power system available.
- Output
- Output Circuit:The output of the test set is easily adjustable from zero to the maximum current available through the impedance of the device under test. Two output ranges are provided to accommodate a variety of load circuit impedances.For high impedance devices, the output can be connected in series (with the series bar provided) to double the output voltage at a reduced maximum current.The maximum current available from the test set is determined primarily by the impedance of the load circuit.The duration of the available current is determined primarily by thermal conditions within the test set.
- Output Connections: To provide maximum utilization of the output available from the test set, each set is equipped with a Megger stab adapter board and stab sets Model CBS-1 and Model CBS-2 for use with drawout style, metal-clad breakers. The stabs eliminate the significant losses that occur if leads are used to connect the breaker under test to the test set. Cables must be used when testing molded-case breakers or other devices which will not connect directly to the stabs.
- Duty Cycle: The test set will supply the rated continuous current indicated for 30 minutes, followed by 30 minutes off.
- Maximum Output Current: Model DDA-3000/-6000 Series will produce the following outputs at rated input voltage.
