Integrated Recording Units for Transient Fault and Long Term Disturbance Events

Model 1692C Integrated Recording Unit

The Model 1692C Integrated Recording Unit records both transient fault and long term disturbance events with instrument class accuracy, adding a new dimension to power system recording instruments.

Performance

 The Model 1692C features a 16-bit A/D converter per channel and advanced digital filtering techniques to provide outstanding recording fidelity.  An adaptive anti-aliasing filter rejects out-of-band signals to further ensure a high degree of accuracy.  All input channels are DC coupled so that transducers may be monitored and offset currents properly recorded.

Operation

System functions, including virtually all triggering, storage, control and communications are directed by the instrument's Pentium processor, providing optimum flexibility.  This software control allows the user to take full advantage of the powerful facilities.  An external GPS clock may be used to implement synchronous sampling with the degree of accuracy necessary for phasor computation and recording for use in state estimation an protection and control functions.  In addition the data can be used in dynamic stability monitoring applications, load modeling and system model verification.

Configuration

The Model 1692C IRU has a standard configuration of 16 analog input channels and 32 digital input channels in a single compact cabinet.  Other optional configurations are available upon customer request.  For less demanding applications a 12-bit input channel with reduced filtering is provided.
