GDAS-500 Portable 500A DC On-Site Tester/Circuit Breaker Test Set
Circuit Breakers are one of the critical "safety-valves" of electrical systems and basic maintenance procedures are essential to maintain maximum reliability.
According to the actual situation of the DC circuit breaker ampere-second characteristic test system, our company has introduced a DC circuit breaker ampere-second characteristic test system suitable for substation site use, easy to carry, and high degree of automation. It can provide DC protection for the operation and maintenance department. Characteristic testing methods are used to verify the action characteristics and level difference coordination of DC protection appliances, so as to improve the reliability of the DC system operation and ensure the safe and reliable operation of the power grid.
Features
- 320*240 LCD screen, thermal printer, interactive keyboard operation, and intelligent operation system.
- Power electronics controlling technique has been adopted to output high current, which is high speed, high precision and continuous adjustability.
- Current range can be automatically switched by multiple high precision sensors.14-digit AD acquisition chip of high capacity.
- Automatic data storage. Be capable of saving 200 testing results, which will not lose in power failure.
- Optional for ampere-second characteristic test (action test) or through current characteristic test (non-action test).
- Protection functions for overheat, over-current and over voltage. Anti-interference capacity and good EMC (electromagnetic compatibility).
