# AN403: Using Arbitrary/Function Generators to Simulate Polyphase Power Line Waveforms

GENEVA, OH, October 10, 2015

Polyphase signal generation is required for a broad range of test applications. For example, it is used in condition monitoring or fault detection systems. These tests require the simulation of three-phase sine waves with line frequencies, ranging from 50 – 800 Hz, where fault conditions or high frequency noise are introduced. Three-phase AC power supplies may be considered; however, they are restricted by bandwidth limitations, cost and the inability to recreate real-world waveforms. TEGAM’s 2700A series arbitrary/function generators address the synchronization, phase shift and resolution issues and are ideal for simulating pulse, noise, sensor stimuli, speed profiles or faults.
