Welcome to Softstuf.com

Softstuf, founded in 1991, is a Philadelphia based corporation that specializes in the design of advanced analysis systems for measuring performance of large electrical power systems during fault and disturbance conditions. Softstuf is the home of the Wavewin software and the Sniffer data acquisition tools.


The Automation routines are a set of rules and methods used to measure 3 types of abnormal circuit conditions: imbalance, overload and inefficiency in a periodic load file. When the load file is processed 4 analog channels and 5 digital channels are created in the file:

Analog Channels:
  • Max Rating The max rating channels displays the defined maximum rating.
  • I Average The I Average channel displays the average value from the IA, IB and IC channels.
  • I Max The I max channel displays the maximum value from the IA, IB and IC channels.
  • Derivative The derivative of the power factor channel.
Digital Channels:
  • Breaker Status The breaker status channel is marked as triggered when a sample indicates an OPEN in the breaker status field (BRK).
  • Data Integrity The data integrity channel is marked as triggered when the date and time for a sample are invalid and the difference between the current samples and the previous samples are greater then 5 times the defined rating.
  • Imbalance The imbalance channel is marked as triggered when an imbalance condition is detected.
  • Overload The overload channel is marked as triggered when an overload condition is detected.
  • Inefficiency The inefficiency channel is marked as triggered when an imbalance condition is detected.

An adaptive learning scheme is used to tune the time varying coefficients (W1, W2 & W3) of an imbalance, overload and inefficiency summation equation. The equation is used to classify circuit conditions (i.e., assign priority values).

  • Monitor Evolving Loads
  • Detecting Good/Bad Circuit Conditions
  • Imbalances, Overload & Inefficiency
  • Station Summaries
  • System Summaries
  • Automatic Prioritization of Circuits
