Transformer Turns Ratio Meters
-
Vanguard Instruments Company, Inc.
The ATRT-01 S3 is Vanguard’s fourth generation, micro-processor based, single phase, automatic transformer turns-ratio tester. The ATRT-01 S3 uses the IEEE C57.12.90 measuring method to determine the transformer turns-ratio. The transformer turns-ratio is determined by precisely measuring the voltages across the unloaded transformer windings. The ATRT-01 S3’s measuring circuitry self adjusts before each measurement to ensure turns-ratio accuracy. Two selectable test voltages, 4Vac and 40Vac, offer flexibility in testing different types of transformers.

Computer Conversions Corporation
The SCT Series are low cost, miniature, solid state control transformers designed for military and industrial control applications. They will directly replace conventional electromechanical control transformers & thus provide digital control to existing analog servo systems. They simultaneously accept a 3 wire synchro input (0) and a digital angle input (0), and provide an ouput which is the sine of the difference between these two input angles (A sin wt sin (0-0) ("wt" is the synchro excitation frequency).

Three-Phase Transformer Winding Resistance Meters
TWA Standard Series
-
When it comes to winding resistance measurement on three-phase power transformers and autotransformers, TWA Standard series offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization. The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.Both models can output test currents from 5 mA to 25 A DC for the purpose of winding resistance measurement. TWA40D has a special test mode for checking the synchronization of on-load tap changers with three phases simultaneously tested in parallel, in which the total test current can rise to up to 40 A DC.TWA40D has additional advantages when it comes to non-intrusive tap changer analysis. The unique DVtest method enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, simultaneously with the measurement of tap changer motor current which helps with the detection of motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or on three phases simultaneously. It can also be performed as an additional test simultaneously with the winding resistance test in all tap positions.An additional unique advantage of TWA40D is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer (connected in a YN configuration). This can significantly shorten the total testing time – for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.The test leads for TWA three-phase transformer winding ohmmeters are interchangeable with the TRT turns ratio testers, which means that both sets of tests can be performed with a single test lead connection to the power transformer terminals.

Transformer Winding Resistance Meters
TWA Advanced Series
-
The TWA advanced series instruments are designed for six-winding resistance measurement and simultaneous three phase on-load tap changer analysis of both the primary and the secondary transformer windings. This is performed with a one singlestep cable setup, with test currents of up to 40A. Each transformer configuration has a special measurement algorithm which is optimized for the fast stabilization of test results. The TWA instruments generate a true DC ripple-free current. Both the injection of the current and the discharge of energy from the magnetic circuit are automatically regulated.

System Test
-
Testing a complete system is very different from unit and integration test. It starts with the V model that defines the system requirements, and this needs an effective system test capability that includes both the system and the environment around it. If the system has interfaces to the outside world, communications links or human control, these interfaces have to be tested.

Accolade Engineering Solutions
As new products employ advanced materials and processes, the need to measure and characterize those material properties becomes increasingly important. DSC is used to measure heat flow in to or out of a material. Some DSC applications include measurement of melting temperature, polymorphic transitions, crystallization temperature, thermal stability, heat of fusion and degree of cure. TMA is used to measure dimensional changes of a material as a function of temperature.
