Thermal Load Boards
-
Thermal Engineering Associates, Inc.
A Thermal Load Board (TLB) is used to simulate an application printed circuit assembly (PCA) either before all the heat-producing components are available for mounting on the application PCA or if the heat-producing components require complex electronic circuitry to create heat within the components. The TLB is typically designed to be as mechanically and thermally equivalent to the application PCA and usually offers a way to vary the power dissipation of the elements that simulate the heat-producing components.

Moisture Resistance/ Humidity Test
-
This test is performed for evaluating the resistance of component parts and constituent materials to the deteriorative effects of the high-humidity and heat conditions typical of tropical environments. Most tropical degradation results directly or indirectly from absorption of moisture vapor, and from surface wetting. These phenomena produce many types of deterioration, including corrosion of metals; physical distortion and decomposition of organic materials; leaching out of constituent components of materials, and detrimental changes in electrical properties.

Femto / Picoammeter and Electrometer / High Resistance Meter
B2980A Series
-
Both the picoammeters and electrometers provide a world-best performance of 0.01 fA (0.01 x 10-15 A) current measurement resolution. In addition, the electrometers can measure resistance up to 10 P (10 x 1015 ), which is also a best-in-class specification. Finally, since AC power line noise can be difficult to eliminate when making low-level measurements, both the picoammeters and electrometers are available in battery powered versions.

Three-Phase Transformer Winding Resistance Meters
TWA Advanced Series
-
TWA Advanced series is the latest DV Power solution for three-phase transformer winding resistance measurement and tap changer analysis. They are capable of testing six transformer windings with a single cable connection, as well as three-phase automatic transformer demagnetization. It has the option of the automated test mode, where the instrument operates the tap changer without operator input (minimizing the risk of human error) and records winding resistance results based on pre-selected stabilization criteria.The unique DVtest method of tap changer analysis 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, together with the measurement of tap changer motor current which detects 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 simultaneously on three phases. It can also be performed together with the winding resistance test in all tap positions.A unique advantage of TWA Advanced instruments 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 speed up the testing– for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.TWA500 is equipped with a large 10.1” graphical touch-screen display, while TWA400 has a 7” graphical touch-screen display. Besides making the interface much more user-friendly compared to older winding ohmmeters, it also enables certain test options that were previously available only with DV-Win software. The most important among them are DVtest, tap changer motor current measurement, “Heat Run” test, test templates, and automatic test mode.

Resistance Grounded Systems (HRG/LRG)
-
Neutral Grounding Resistors (NGRs) are used to limit the maximum ground-fault current. Restriction of fault current lowers hazards and reduces damage done to equipment. High Resistance Grounding (HRG) systems are often used on industrial and critical power applications to maintain system uptime during a first ground fault. HRG systems are also used in tripping applications to help control touch potential on portable loads and improve personnel safety.
