Grounding Group DC Resistance Tester Specifications
In the power system, the portable short-circuit grounding line and the personal protection grounding line play a crucial role in preventing the power equipment, the circuit from suddenly calling and eliminating the induced voltage, and discharging the remaining charge. In order to prevent unqualified ground wires from entering the power system, our company has developed a grounding wire according to the "Technical Standard for Portable Short-Circuit Grounding Wires" and the "Prophylactic Experimental Procedures for Power Safety Industrial Appliances" issued and implemented by the State Power Corporation. A group resistance tester" provides services for the power system to perform necessary product preventive tests.

Resistance Electrothermal Alloy
High resistance alloy is used to produce resistance elementof conductive material.Requirements including High mechanical strength, good corrosion resistance and oxidation resistance. Working temperature is usually at500 ℃. Commonly used with constantan chromium iron, iron chromium aluminum, nickel chromium, nickel, resistivity rho (20 ℃) is 1 Ω was/m or so. It is not used in the conduction of current, but with its high resistance to limit or control the current in the circuit, such as motor, potentiometer, standard resistors, potentiometers, slip line resistor resistance element and resistance line, etc.; For the using of high resistance in the pressure sensor,Temperature compensator and temperature measuring resistor of resistance element to creatte reflect strain, temperature, magnetic field and parameters; High resistance alloy can also be used as heating elements in the manufacture of the resistance heating equipment, could be applied in current, voltage regulating and the winding of control components.
