  • Impulse Testing and Turn Insulation Deterioration in Electric Motors
    Impulse testing is an integral part of predictive maintenance of electrical motors. Through the following questions the influence that extensive impulse testing has on a motor is investigated. Can impulse testing damage healthy or deteriorated insulation? Can DC Resistance, Inductance, Megger
  • Impulse Response of 900-Series Biaxial Clinometers Jewell
    The impulse was generated by rotating the clinometer through an angle of 3.4 degrees by pulling a gage block out from under one end of a Model 791 Tiltmeter Calibration Plate. The test was reproduced at three different temperatures using clinometers with undamped (non-viscous liquid) and critically
  • Using Surge Testing as Predictive Technology
    : The AWA (automatically) applies a number of successive surge pulses to a motor. Each successive impulse is applied at a slightly higher test voltage than the previous pulse. The test voltage starts at zero volts and goes up to a user defined maximum test voltage. The AWA will digitize each surge
  • Solid-State ac Power Sources for Transformer Testing
    High-power electronics can now replace motor-generator sets for testing distribution transformers. * Solid-state ac-power sources combine the variable-frequency and voltage-power sources into a single package. * Tests sets are hardened against impulse events like those caused by lightning-strike
  • Measuring the Vibrational Behavior of a Baseball/Softball Bat
    using rubberands. This provides some stability so the bats won't bounce around during testing, but doesn't prevent the bats from vibrating. I use a special impact hammer to provide the input force - the hammer has a force transducer in the head so as to measure time history of the force impulse when
