Ground-Fault Products for Solidly Grounded Systems
Ground-fault products are used to monitor grounded systems (ungrounded and grounded) for fault currents or residual currents. The sum of all conductors except the protective earth conductor is measured by means of measuring current transformers.In general, ground-fault monitors (RCM - residual current monitors) are used to send a message to the user even before reaching the shutdown threshold of the GFCI. Ground-fault monitors detect deteriorations of the insulation level at an early stage and in a reliable way.

Electrical Resistance (ER) Monitoring
The electrical resistance (ER) technique is an "on-line" method of monitoring the rate of corrosion and the extent of total metal loss for any metallic equipment or structure. The ER technique measures the effects of both the electrochemical and the mechanical components of corrosion such as erosion or cavitation. It is the only on-line, instrumented technique applicable to virtually all types of corrosive environments.

New Resistivity Inversion Software
EarthImager 3D
AGI is proud to introduce the new EarthImager 3D resistivity and IP inversion software. This software inverts resistivity and IP data acquired with electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible. With EarthImager, 3D resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks.

Resistance Welding
Resistance welding is a method in which the welding works are heated by resistance heat generated by sandwiching the welding workpieces with welding electrodes, passing current through them, and the metal is welded while pressurizing the works.A resistance welding machine composed of welding power supply, a weld head and an electrode. The welding power supply controls a welding current,the weld head exerts a pressure on the material to weld and the electrode provides welding current and pressurization force to the part under welding. We have been providing various kinds of welding power supplies and welding heads to meet these requirements.
