Transformer Test Equipment
DV Power test instruments perform various diagnostic tests on power and instrument transformers. Even more, a unique feature is a condition assessment of on-load tap changers. Performing a transformer test before their breakage can be crucial.Test instruments are portable and enclosed in durable metal cases. Also, the 19” rack-mounted version suitable for factories is available as well.Applications supported by DV Power transformer test equipment include:Winding resistance measurement (IEC 60076-1)Analysis of on-load tap changers (IEC 60214-1)Heat run test (IEC 60076-2)Automatic transformer demagnetizationTurns ratio measurement of power and instrument transformers (IEC 60076-1)Excitation current measurementPhase angle measurementTransformer vector group detectionDemagnetization status verificationAll of the above-mentioned measurements are performed with the highest accuracy.The advanced DV-Win PC software collects both numerical and graphical results. As a result of that, these features provide an easier and more efficient analysis. After the test, DV-Win software generates a test report with a single click. Furthermore, a user can easily customize the test report and save it in different formats, such as XLS or PDF.Finally, the analysis of on-load tap changers is performed by the new method called dynamic resistance measurement (DRM). This is a non-intrusive method. Therefore, it allows detecting problems in on-load tap changers without disassembling them.

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.

High Voltage Isolator for Logic Analyzers
LX-08
The LX-08 series of high voltage logic analyzer adapters provides a safe isolated method of measuring high voltage control signals with a low voltage logic analyzer. All inbound signals are optically isolated and attenuated to a safe level for the delicate inputs typically found on logic analyzers. The inputs on the LX-08 are capable of withstanding voltages up to +/- 300V AC/DC, higher voltage configurations are available upon request. Rather than probing with multiple neon screwdrivers, the LX-08 can provide simultaneous viewing of up to 8 circuits in the STANDALONE mode via the indicator array. Need to catch a transient event or map out a timing sequence? Just add a logic analyzer to the outputs of the LX-08 and turn it into a high voltage logic analyzer. High voltage signals that were hazardous for a logic analyzer can now be measured safely. Typical outputs of a high speed PLC sequencer can be precisely timed and measured from both sides of the control relay. With the built in user selectable AC filter circuit, an AC signal can be measured as DC events or AC cycles.

PWM TO VOLTAGE SIGNAL CONVERTER
RCPWM2V
The RCPWM2V is a device that converts a standard hobby RC signal (1-2ms pulse) into a proportional analog voltage (0-5V). In many electronics applications the main processor is constantly busy and does not have the ability to address the time-sensitive PWM signal from an RC receiver immediately. This results in signal distortion or a sluggish response due to the extra filtering required. The RCPWM2V provides a simple solution by converting the signal into an analog signal. The main processor can then read the signal whenever it has time.

Dielectric Withstanding Voltage Test
The dielectric withstanding voltage test (also called high-potential, over-potential voltage-breakdown, or dielectric-strength test) consists of the application of a voltage significantly higher than rated voltage for a specific time, between mutually insulated portions of a component part or between insulated portions and ground. This is used to prove that the component part can operate safely at its rated voltage and withstand momentary over-potentials due to switching, surges, and other similar phenomena.
