Contact Resistance Tester
-
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.

Loop Resistance Measuring Device According to DIN EN 61557-3 (VDE 0413-3)
-
PeakTech Prüf- und Messtechnik GmbH
A loop tester which is used to test the safety of electrical systems. These device measures the impedance of the short-circuit loop between the outer conductors of a circuit, whereby the probable short-circuit current is calculated. The protection of the circuit (miniature circuit breaker) must therefore trigger at a lower current than the expected short-circuit current, in order to avoid excessive heating of the lines and thus a fire risk. The PeakTech 2715 is due to its function and its robust design almost indispensable when performing new installations, but also for general checking of electrical systems, this device is the ideal companion.

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.

4-Wire Resistance Measurement | Continuity & HiPot Cable & Wire Harness Testers
-
An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty crimps, recessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire.This option may be purchased with any new HVX tester, or added as an upgrade to any of your existing HVX testers.

[5kV AC/6kV DC] Hipot and Insulation Resistance Tester, Rise/Fall-Time Control Function Equipped
TOS5300 Series
-
The "TOS5300 Series" is a series of test instruments used in Hipot (withstanding voltage) tests and insulation resistance tests, two of the four tests regarded as necessary for ensuring the safety of electrical products. With an output of 5 kV/100 mA (AC) and 6 kV/10 mA (DC), the series can be used in Hipot (withstanding voltage) & insulation resistance testing of electronic equipment and electronic parts, based on the requirements of IEC, EN, UL, VDE, JIS, and other international safety standards and the Electrical Appliance and Material Safety Law. Also, the test voltage stability is improved with the adoption of a newly developed switching amplifier. Since the output voltage can be kept constant even when the AC line voltage or frequency changes, consistent testing can be performed, even when the power supply environment is in an unstable region. The TOS5300 is also equipped with a number of features that are capable of meeting a variety of test needs. It is a new low-cost standard model that provides thorough operability, reliability and safety.
