Magnetic Field and Permeability Measurement
MAGNETOSCOP® 1.070
-
Foerster Instruments, Incorporated
The MAGNETOSCOP 1.070 is a portable magnetometer system with microprocessor and probes for measuring the magnetic flux density as an absolute or differential value (gradient). It has a USB port for simple data transfer and an SD card for saving measurement data and parameters. The measuring system also facilitates the recognition and saving of peak values and the adjustment of thresholds for limit values. The unit can be used for series and individual measurements. The data can be easily analyzed and documented with the PC software included in the scope of delivery. The MAGNETOSCOP 1.070 thus facilitates the portable and fast measurement of the relative permeability within the scope of the quality control of stainless steel and low-permeable (non-magnetic) alloys as well as the localization of ferrite enclosures. Changes in material (sulfidation, degradation of lamination, structural changes) can also be proven thanks to permeability comparative measurements.

Ground Grid Tester
GGT Series
-
The GGT500 ground grid integrity tester is designed for inspection of the substation ground grid. It can also be used as a portable micro-ohmmeter with Both Sides Grounded and Remote Control functionalities. It is intended to inspection the conditions of a grounding system beneath substations, testing of medium- and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links.In the United States when inspecting the quality of the grounding systems beneath a substation, the proper procedure is to inject 300 A DC during a time period of 60 s. This is what the GGT500 will do, and in that time period, the current path and voltage drop are checked. Also acting as a micro-ohmmeter, the GGT500 can test low resistance values by producing high test currents of up to 500 A.The instrument is placed in an unbreakable, plastic case with IP67 protective rating (with closed lid). Although very portable and lightweight, micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents, as well as the use of thinner/longer test cables. GGT500 ground grid integrity tester generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. This significantly decreases magnetic transients and ensures great accuracy.When used for testing in Both Sides Grounded conditions, a special current clamp powered from the ground grid integrity tester is used for measuring a current through groundings. If even a higher safety level is required, the remote control feature enables the operator to perform measurements from a distant location, away from the instrument and test object.

Fluxmeters
-
Flux meter has been the established standard for the measurement of magnetic flux density for determining total flux in a magnet or magnetic assembly. Its use was curtailed except in a few specialized areas because of many factors such as the difficulty in setting up light beam flux meter or ballistic galvanometers, limitations on the ohmic resistance of search coils, the requirement of some degree of operator skill in reading the flux meter etc. The development of the integrating type Digital Flux meter has virtually cancelled the hitherto negative aspects of fluxmeterology and has found a broad niche for many magnetic measurement applications.

Transformer Ratio Meters
Handheld Turns Ratio & Winding Resistance Tester TWR-H
-
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.
