KRI 9310 adopt Kelvin four-wire testing method, which effectively eliminates the influence of the resistance of the test line on the test results. It can be able to increases the current to 10A by which can test extremely low resistance to 0.01 Ω(such as amorphous alloy, Copper-nickel, nickel-chromium-iron, iron-chromium-aluminum etc). For the tested objects with high resistance value (CT/PT), the instrument can extend the range to 20 kΩ，so the wide resistance test range enables KRI9310 can cover 80% of the power transformer products on the market and switchgear bus-bar cable etc. The power of the tester use the built-in rechargeable lithium battery that can test hundreds of transformers by one time charging.

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.

High Impedance Transformers
-
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.

Step Up Transformer
MagD
-
SCOPE proudly introduces Step-Up Transformer - MagD, specially designed to cater the needs of testing of instrument Transformers. Before new systems are put into service or after any occurrence of fault, the instrument transformers need to be tested for their outputs. It is to be ensured that these instrument transformers are giving proper outputs to the protective relays. MagD is used to plot excitation curves for instrument transformers. Inbuilt voltmeter and ammeter, eliminates the need of external meters for plotting of curves. It can also be used for de-magnetization of transformer cores and also turns-ratio tests can be conducted using MagD.

BMS Transformers
-
In large battery pack applications with daisy chain connections, the number of cells connected in series is very high, and the large voltage differences demand component-to-component isolation. The serial communication links between boards need to be isolated by transformer coupling circuits instead of capacitor coupling.

Oil Tan Delta Tester
OTD
-
The Oil Tan Delta (OTD) is a laboratory instrument, which measures the Tan Delta, Resistivity and Relative Permittivity of insulating liquids. These tests give a wider picture of the overall quality of the insulating oil, and will indicate if there is any contamination. Megger has developed features of the OTD to ensure that productivity levels within laboratories are maximised. The microprocessor controlled inductive heater means that there is uniformity of temperature throughout the cell, in compliance with IEC 60247, and for cooling a fan effectively speeds up the cell cooling time. The instrument has a temperature measuring range of 10 to 110 C, with an accuracy of 1 C. It can be set to preheat before testing takes place. The automated oil drain facility negates the need to move the oil vessel. User safety is paramount and with this in mind, Megger have designed independent and dual redundant high voltage cut-off circuitry. If for any reason the user needs to abort the test, this can be done so by pressing any key, immediately terminating the test and removing the high voltage. The design of the cell components maximise oil fill rate but minimise turbulence in oil flow and eliminate trapping of air. With only 32 cell components, it is easy to assemble and disassemble.

AC Test Transformer
-
Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.
