GDAS-500 DC Circuit Breaker Ampere Second Characteristics Testing System
Product Overview
Execution standard: DL/T 5044-2003
Based on the current situation of testing the ampere second characteristics of DC protection devices, our company has launched a DC circuit breaker ampere second characteristic testing system that is suitable for on-site use in substations, easy to carry, and highly automated. It can provide a testing method for the action characteristics of DC protection devices for operation and maintenance departments, verify the action characteristics and level coordination of DC protection devices, in order to improve the reliability of DC system operation and ensure the safe and reliable operation of the power grid. This testing system is suitable for testing the ampere second characteristics of DC protection devices with rated currents ranging from 1A to 500A, and can also be used for testing the ampere second characteristics of DC protection devices with rated currents ranging from 6A to 100A.
