InSight™ IR Portholes Overview

The National Fire Protection Agency (NFPA-70E) provides stringent guidelines for wearing Personal Protective Equipment (PPE) when the deadfront is open and the operator is exposed to live bus. The use of IR Scan Portholes allow the operator to leave deadfronts closed during the IR Scan operation.

InSight™ IR Portholes are openings in LayerZero units with hinged covers for ease of thermal scanning of all bolted connections. Thermal scanning bolted connections is a common procedure for preventive maintenance.

The covers of InSight™ IR Portholes swivel outward to reveal a mesh. The mesh helps protect operators, while ensuring full functionality of thermal scanning ability. The usage of InSight™ IR Portholes makes it safer for operators to measure bolted connections.
