The medium-voltage controllable fuse provides arc-flash
protection with a plug-in retrofit to existing medium-voltage
fuses at low total cost and with minimal installation downtime
and ownership maintenance. The unit is designed to mitigate
the arc-flash hazard on the low-voltage side of a medium-voltage
transformer. The fuse was developed in response to OSHA Code
29 CFR-1910 Subpart S, requiring employers to identify and analyze
arc-flash hazards and provide adequate personal protective equipment.
Precision Pressure Calibrator
The model 721Ex intrinsically safe precision pressure calibrator has
dual-isolated pressure sensors with reported 0.025 % accuracy. The
calibrator is rated IECEx and Atex Ex ia IIB T3 Gb (Zone 1) for safe
operation in hazardous environments with potentially explosive
atmospheres. It performs simultaneous static and differential pressure
measurements, making it useful for gas custody transfer calibration.
The 721Ex eliminates the need to declassify work areas during calibration and allows technicians to perform gas custody transfer measurements without hot-work permits.
