Frequently Asked Questions (FAQ)
**Q1: What circuit breakers can the MSKC-HA test?**
A: SF6, GIS, vacuum and oil circuit breakers from all major manufacturers.
**Q2: Does it need an external power supply?**
A: No. The MSKC-HA has a built-in DC6~270V adjustable power supply, 20A.
**Q3: How many fractures can it measure at once?**
A: 12 fractures — 6 main and 6 auxiliary contacts.
**Q4: Can it measure speed without retesting?**
A: Yes. Speed can be recalculated from the same test data without re-operating the breaker.
**Q5: Is it suitable for 500KV substations?**
A: Yes. The internal anti-interference circuit is designed for reliable use in 500KV substations.
**Q6: What sensors are supported?**
A: Linear, rotation, universal and laser sensors (optional).
**Q7: How is data exported?**
A: Via 2 USB ports (U disk or mouse), RS232 (optional) and WIFI (optional).
**Q8: What is the warranty and support?**
A: Contact Magus for warranty details and technical support.
