A reading of 9 drops in 5 minutes would be categorized as which?

A reading of 9 drops in 5 minutes would be categorized as which?

• A. GT running leakage
• B. GT leakage
• C. GT seepage
• D. Weepage

Answer: (B)

When evaluating leaks in gas turbine systems, you classify by how fast the leakage is and whether it occurs during operation or while the machine is idle. A measurement of 9 drops in 5 minutes means roughly 1.8 drops per minute, which is a noticeable leak rate, not just a trace. Weepage and seepage describe very small, slow leaks, while running leakage refers to leaks observed while the turbine is operating. Since the reading shows a clear, measurable leak but isn’t described as occurring during operation, it fits the general GT leakage category.
