Current And Voltage Input Sensors
-
Current input sensors monitor current from inverters in solar panel and wind turbine applications and turn the current into voltage which can be measured with an analog input type data acquisition module for analysis. Voltage Input Attenuators can be used to measure high voltages. Voltage Attenuators are designed for used in high-voltage applications. The current can be converted into +/-10 Vpp attenuated signal, so that a general electronic measuring device is able to read the signals.

Injection Transformer
J2100A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.

Device Current Waveform Analyzers
-
The dedicated Current Sensors measure from 100 pA level dynamic current up to 10 A with a maximum of 200 MHz bandwidth. The mainframe acquires the signal from the sensors by a maximum of 1 GSa/s sampling speed and 14-bit and 16-bit wide dynamic range. This combination allows you to measure quite wide range of dynamic current, for example, from standby/sleep state to active state, at a single measurement. In addition, the wide bandwidth and the high speed acquisition enable you to measure high speed pulse response even less than 100 ns previously very difficult with existing instruments.

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.
