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.

Single-Phase Transformer Winding Resistance Meters
RMO-TW Series
-
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.

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 resistanceDRM (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 contactsSynchronization between the contactsMotion and velocity“First trip” testThe 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.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

-
BXL is an extra load unit designed to be used with DV Power’s BLU series battery testers. However, this unit is a universal add-on device. Because of that, it is compatible, as an additional load, with any other discharge/capacity tester in the market.In case when discharge current exceeds the capacity of a single BLU device, BXL can increase the discharge capacity. There are no limitations on the number of extra load units that can be connected in parallel to the main battery tester.A system of BLU and BXL instruments enables performing the capacity test in an accurate, user-friendly way. Also, all instruments are in accordance with battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.These units can be used on any type of battery string, such as lead-acid, Li-Ion, Ni-Cd, etc. They test battery strings with voltages in the range of 5,25 – 500 V DC. On the other hand, current up to 250 A can be discharged through the BXL internal structure.The instrument simulates a constant resistance load during the discharge test. Several resistances can be set for different battery nominal voltage levels. This makes BXL extremely flexible in selecting its load capabilities.
