Total Energy System
5000
-
The electric vehicle (EV) charging market is rapidly expanding, with more and more people switching to electric cars. As the demand for EV charging stations increases, so does the amount of energy that is being exchanged. This energy exchange market is already massive, with charging peaks reaching into the megawatts of energy. With this amount of energy comes a significant amount of revenue, which requires the most accurate billing possible. That’s where TESCO’s Catalog No. 5000 – Total Energy System comes in. The Catalog No. 5000 is a double duo system that enables the testing and accuracy verification of Electric Vehicle Service Equipment (EVSE) and Field Test Equipment for testing EVSE’s in the field. This system is a dual-purpose DC and AC System and includes both a 100A AC (ACT-100) Test System and a 200A DC Test System (DCT-200).

Magnetoresistive Milligauss Meter
MR3
-
The MR3 Magnetoresistive Milligauss Meter measures and displays the three vectorcomponents (X, Y, Z) as well as the magnitude (M) of the static magnetic field. Update is two times per second. The three sensors are in a 25 mm (1") cube at the end of a flexible 100 cm (40") cable. It can be powered by 4 AA batteries (included) or a Worldwide AC adaptor (included). It can collect and store data (X, Y, Z and M) for later download or stream data live via USB connector. Both the instantaneous values of X, Y, Z and M, and their peak values, are displayed on the meter screen. "Peak" values are the highest values seen since the peak reset button was pressed. Maximum error of sensitivity is +/- 0.5 % of the reading, and the maximum error of the offset is +/- 0.50 milligauss. Range is +/- 1999.99 milligauss with resolution 0.01 milligauss (or 1 nT) over the full range, displayed simultaneously for X, Y, Z and M.

Localized Electrochemical Impedance Spectroscopy
VS-LEIS
-
The VersaSTAT 3F applies an AC voltage to the sample emerged in electrolyte. This "global" voltage generates AC current to flow at the electrode / electrolyte interface. A dual-element probe is positioned in solution close to the surface of the sample. The electrometer measures a differential voltage measure between the two measurement elements as a measure of local voltage-drop in solution. This voltage-drop exists in solution because of current flow from local reactions at the sample, the resistance of the electrolyte and the spatial separation of the dual measurement elements.

Turns Ratio Testers
TRT Standard Series
-
When it comes to choosing a transformer turns ratio tester, TRT Standard series offers some of the most advanced instruments with LCD display out in the market. Each model measures transformer excitation current and phase shift performs automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. Furthermore, they have a built-in true three-phase power source. Because of that, TRT Standard instruments can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 250 V AC, depending on the chosen model. High test voltage of 250 V AC provides more accurate turns ratio testing compared to other turns ratio testers on the market and extremely low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT Standard series consists of:TRT03 Models (TRT03A, TRT03B, TRT03C) – single-phase voltage up to 100 VTRT3x Models (TRT30A, TRT30B, TRT30C, TRT33A, TRT33B, TRT33C) – single and true three-phase voltage up to 100 VTRT63 Models (TRT63A, TRT63B, TRT63C) – single and true three-phase voltage up to 250 VMore about models differences can be found under the downloads tab, in brochures and comparison sheets.A user can create test templates using the DV Win software and store them in the PC’s memory for later use when in the field.TRT Standard series models have a built-in tap changer control unit. Consequently, it enables remote control of an on-load tap changer (OLTC) directly from the tester. In order to make the most out of this feature, the DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time.
