DV Power Circuit Breaker Test Equipment

For Medium and High Voltage

Circuit Breaker Catalog

DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.

Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.

Applications supported by the DV Power test equipment include measurements of:

  • Contact resistance
  • DRM (dynamic resistance measurement)
  • Coil resistance and coil current (IEC 62271-100)
  • Mechanism charging time (IEC 62271-100)
  • Minimum trip voltage (IEC 56, ANSI C37.09)
  • Undervoltage release (IEC 60694)
  • The timing of a circuit breaker’s main, auxiliary and pre-insertion contacts
  • Synchronization between the contacts
  • Motion and velocity
  • “First trip” test

The essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.

DV Power Transformer Test Equipment

Low, Medium, & High Voltage

Transformer Catalog

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)
  • CT/PT/CVT test w Multi-tap built-in
  • Automatic transformer demagnetization
  • Turns ratio measurement of power and instrument transformers (IEC 60076-1)
  • Excitation current measurement
  • Phase angle measurement
  • Transformer vector group detection
  • Demagnetization status verification
  • All 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.

DV Power Battery Test Equipment

Battery, String and Cell Maintenance

Battery Test Catalog

Improper functioning of battery systems installed in utilities, power plants, telecommunication systems, industrial applications and etc., can cause severe failures of the supported equipment and loss of critical information. Therefore, the battery test verifies their actual SOC (State of Charge) or SOH (State of Health) and prevents unwanted scenarios which could result in a significant budget loss as well as endanger of human lives.

DV Power battery test equipment is able to perform the following battery measurements, using BLU and BVR devices:

  • Voltage (String and Cell)
  • Capacity
  • Temperature
  • Detect weak cells via load test

All of the above-mentioned measurements are performed with the highest accuracy. The advanced DV-B Win PC software enables collecting both numerical and graphical results. These features provide an easier and more efficient analysis. After the test, DV Win software generates a test report with a single click. A user can easily customize the report and save it in different formats, such as CLS, PDF, Word, or RTF.
