How to configure IP PA zones for a power plant with separate HT and LT switchgear rooms?
Industry: power plant | Architecture: IP
High-voltage switchgear environments present intense electromagnetic interference that can disrupt PA equipment. The BNA 9000-i125-HA IP server in the dedicated server room manages electrical area zones. Shielded Cat6A Ethernet cables carry the IP PA signal to BNA IP-H15-POE speakers in GIS rooms and MCC floors, maintaining signal integrity in high EMI environments. BNA 9200 IP field call stations at electrical area access doors enable the safety officer to page maintenance teams before energizing or de-energizing breakers. Earphone socket-equipped BNA 9200 stations allow maintenance personnel to receive PA audio without affecting others nearby — important in sensitive switchgear rooms where unnecessary audio is discouraged. BNA 9100 SIP master station at the electrical maintenance chief's office coordinates all high-voltage work clearance paging. All communications are logged with timestamp for electrical safety permit audit.
Technical Details
- Environment: power plant electrical area with 220kV GIS, 11kV switchgear, and LT MCC rooms
- Constraints: EMI-intensive environment, access-restricted zones, safety interlocks needed
- Requirement: safety paging for maintenance in high-voltage areas and switchgear rooms
