NB/T 20197.3-2014Reliability and aging detection for instrumentation and control equipment in nuclear power plants - Part 3: Power supply (English PDF)

NB/T 20197.3-2014 is the English-translated version of 核电厂仪表和控制设备可靠性及老化检测 第3部分：电源.

NB/T 20197.3-2014 is the recommended Chinese energy industry standard dealing with the power supplies that serve instrumentation and control systems in nuclear power plants.

As Part 3 of the NB/T 20197 series it covers the AC or DC energy conversion devices which provide stable power to instrumentation and control equipment, setting the parameters of those devices and the methods used to detect their reliability and their ageing.

The work it governs is the qualification of the power supply itself rather than the controlled process behind it, and it is classified with nuclear power plant instrumentation in the international scheme.

GB 4943.1-2011 is the standard it calls up. Issued on 29 June 2014, it has applied since 1 November 2014.
