This paper introduces an intelligent instrument for integrated harmonic detection,analysis and protection. The hardware structure and software modules are described in detail.Some key techniques and skills used in the development of hardware and software are put forward,for example,FFT calculation method and skill,expert prediction control in fault wave recording and three-dimensional projection technique etc. In the end,the main functions of the instrument are introduced.The instrument has been putinto trial operation in some substations.The results show thatitcan detect,analyze and automatically record the harmonic parameters accurately and reliably.
