Site Test Report Date: Al-Osais Co. KHUDARIYAH S/S 115/13.8 KV S/S CT Supervision Relay - MVTP

An on-site test report for a CT supervision relay at the Khudariyah 115/13.8 kV substation documents the mechanical checks, electrical tests, and test results. The relay was found to operate within the specified time of 3 seconds at voltages between 2-16 volts during testing. All output contacts showed resistances below 0.2 ohms and the flag indication and manual reset functions operated as expected. The relay was determined to be in healthy working condition.
