Q: Can the system operate normally in an unshielded, standard factory building? Will the partial discharge readings be affected by the environment?
A: Yes, it can, and they will not be affected
Q: Is the voltage regulator's input power supply three-phase or two-phase? What kind of power distribution cabinet needs to be prepared on-site?
A: Rated input voltage: 380V, two-phase. It must be two-phase; the on-site power distribution system must include a high-capacity (200A) two-phase circuit reserved for this purpose.
Q: What is the internal gas pressure of the equipment during transport?
A: During transport, the SF6 gas pressure should be reduced to within 1.2 Pa (near vacuum).
