PI-41400
-
The PI-41400 is a dual channel Clock Driver card capable of operating up to 190 MHz into a 50-ohm load and up to 80 MHz at an amplitude of 8 volts into a 1-megohm load. Into a high impedance load the output voltage range is from a –3 volts to 8 volts with the output pulse amplitude ranging from 0.5 V to 9 V. When driving a 50 load the voltage range is –1.5 volts to 4.5 volts with the output pulse amplitude ranging from 0.25 V to 4.5 V. The rise and fall times of the output pulse are variable from 1.2 ns to 9 ns into a 50-ohm load and <5 ns to 9 ns into a HiZ load. The output pulse amplitude and the load being driven determine the range of variability. The driver output can be set for tri-state operation and the output polarity can be set for ‘Normal’ or ‘Inverted’ operation through software.

Three-Phase Transformer Demagnetizer
DEM60C
-
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores. The best way to eliminate this source of potential problems is to use demagnetizer on the power or instrument transformer.The DEM60C is a fully automatic test instrument which performs three-phase transformer demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. DEM60C provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. It can demagnetize single-phase and three-phase power transformers.The instrument can be connected to all three phases of a power transformer to be demagnetized, on either the primary or the secondary side. If a user selects specific vector diagrams for different types of transformers, DEM60C will run a specific demagnetization procedure for each transformer type (i.e., single phase, delta, wye/star, zig-zag.) without switching the test leads.DEM60C enables safe and efficient power transformer demagnetization. The instrument automatically regulates the injection of current and discharging energy from the inductance. During and after the operation, an intrinsically safe discharge circuit with an indicator rapidly dissipates the stored magnetic energy. The discharging circuit is independent of the power supply, which improves its reliability in case of loss of power.Test currents of up to 60 A DC enable efficient demagnetization of even the largest power transformers. Using a DV Win software, it is possible to control DEM60C externally.
