Battery Voltage Supervisor
BVS
-
DV Power battery voltage supervisor – BVS, is an accurate battery voltage monitoring system that monitors the state of health of battery systems. It records important battery parameters such as battery voltage, inter-cell connection voltage, and ambient temperature. Because of that, it can be a support tool for capacity testing.The BVS voltage supervisor is an integrated system consisting of:BVS Control Unit (BVS-CU)Cell Voltage Modules (CVM)String Voltage Module (SVM) (optional)String Current Module (SCM) (optional)It is an ideal testing tool for maintenance, troubleshooting and performance tests on individual stationary batteries and battery packs in critical backup energy solutions.BVS-CU provides ambient temperature measurements on multiple locations (4 temperature channels). Overall string voltage and string current monitoring can be achieved by using an optional string voltage module (SVM) and string current module (SCM).There are two types of DV Power battery voltage supervisors:BVS – One cell voltage module measures 1 cellBVS-4 – One cell voltage module measures 4 cellsCVM modules detect cells that fail a discharge test based on monitored voltage values. As a result of that, these cells can be safely removed from the battery string.Data acquisition and analysis of data collected from the modules are available in the DV-B Win application software suite. They provide data viewing, tracking, and generation of comprehensive reports.

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.

Single-Phase Transformer Winding Resistance Meters
RMO-TT Series
-
RMO-TT series is perfect for measuring winding resistance of inductive objects such as power and distribution transformers or autotransformers. Additionally, every transformer resistance meter from RMO-TT series can analyze:tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.Transformer demagnetization can also be performed with all RMO-TT instruments.The series is consisted of 3 models, with maximal test current from 40 A (RMO40TT) to 100 A (RMO100TT). RMO100TT is the only portable transformer resistance meter in the market with 100 A DC output current.The three independent channels enable testing of three windings in series. Consequently, a user can measure winding resistance in every tap position of an on-load tap changer without discharging between the tests.In addition to winding resistance measurement, a user can perform a detailed on-load tap changer analysis by analyzing recorded graphs (10 kHz sampling rate) and by measuring vibrations on an external tap changer tank.All RMO-TT instruments have a built-in tap changer control unit. Because of this, it is possible to remotely control on-load tap changer (OLTC) directly from the device. Also, a user can program DV-Win software to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also 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.All results can be exported in the report format.
