About this file
This document is a Preventive Maintenance (PM) inspection report for Constant Current Regulators (CCRs) located at an electrical vault/substation at coordinates 37.079141, -76.355321 in Virginia, dated April 24, 2026. The report documents maintenance and testing activities performed on airfield lighting equipment, specifically CCRs used for runway approach lighting systems.
The inspection covers 27 CCR units across multiple circuits including PAPI (Precision Approach Path Indicator), runway, approach, and taxiway lighting systems. Key maintenance activities completed include CCR calibration, cleaning, local and remote operational testing, and feedback verification. However, output waveforms were not analyzed and hotspot checks were not performed on the units. The inspection identified firmware versions across the units: CCR Firmware 38A.04, ACE Firmware 28A.07, and IRMS Firmware 32A.04 (with some variations). Detailed measurement data in three appendices provide specific current outputs (I-out) at various step levels (B1 through B5/B100), voltage outputs (V-out), and volt-ampere outputs (VA-out) for each CCR unit, including spare units and empty cells. Notes, conclusions, and recommendations are referenced in an accompanying trip report. Several spare units showed zero output readings, indicating they are not currently operational or in inventory.
