ETAS-500 is a DC breaker ampere-second characteristic tester to adapt field test for transformer substation, providing the test method of Dc protection electrical operation characteristics for operation and maintenance department, and calibrating the characteristics and differential to improve the DC system running stability, ensure the safe and stable running of grid. This tester is special designed for test, repair and maintenance of station, meets the overload and short circuit characteristics test of DC breaker, keeping the DC system of transformer station healthy and avoiding the overstepping trip and large area power failure happen in DC power distribution network.
1. The main control part adopts high-performance industrial PC，Windows XP, display each parameter curve diagram and data in real-time.
2. Keyboard and touch pad input (external USB mouse), 7.48inch TFT real color LCD display. Easy to operate, pretty interface, visual.
3. Adopt switch constant current control technology, new type of power component, setting constant current output from 1~500A with high accuracy, high on-load capability, can work stably for long time.
4. Applied to the test of ampere second characteristic of rated current form 1~500A DC breaker and also 6A~10A DC fuse.
5. The measurement method adopts all-point test or sampling test, with fast response, high test accuracy, safety and reliability.
6. The instrument has the functions of over heat, over current and over voltage protection, good electromagnetic compatibility and strong anti-interference ability.
7. Test management software can automatically complete the ampere-second characteristic test of DC circuit breaker, and analyze the test data to draw the circuit breaker protection characteristic curve (ampere-second curve), and generate report output.
