Something for Nothing hits pay dirt! - Case Study
Challenge: During a scheduled inspection of a facility for a major food processor a number of deficiencies were identified and documented including one ultrasonic class problem within a 12,470 VAC safety disconnect switch (similar to Figure #1 below) feeding a primary side of a main service, oil-filled transformer with a 480 VAC secondary. This was one of two major components that did not make ...

The principle of the industrial metal detector
The industrial metal detector is based on the electromagnetic field theory whose developer is the Scottish physicist James Clerk Maxwell (1831–1879). Maxwell graduated from Cambridge University in 1854 and worked as a teacher in both Marischal College in Scotland and King’s College in London. In 1871 he was invited back to Cambridge University as a professor of Experimental Physics. ...

Animals could help humans monitor oceans
Sharks, penguins, turtles and other seagoing species could help humans monitor the oceans by transmitting oceanographic information from electronic tags. Thousands of marine animals are tagged for a variety of research and conservation purposes, but at present the information gathered isn't widely used to track climate change and other shifts in the oceans. Instead, monitoring is mostly ...

Rogowski Coil Current Sensing Method
In an earlier blog post, we introduced the 6 different current sensing methods used in the current meters and sensors developed by Hioki. Here, we highlight the Rogowski coil method that enables the design of flexible sensors through the use of an air core (or coreless) structure. In a Rogowski sensor, there is no heat generation, saturation and hysteresis due to magnetic loss, and the insertion ...

Verifying the Electrical Potential of Large Equipment
Increase the safety of equipment and systems by reducing the electrical resistance between ground connections (grounds and grounding wires) and metal equipment chassis. Hioki's Resistance Meter RM3548 can play a key role in this important function. When the ground potential of equipment increases, that equipment becomes more likely to malfunction or introduce measurement errors. By keeping the ...

Drone ESC
Choosing a motor/battery/ fpv drone ESC combo is a combination of science, guess-work, and magic! Here is a process to select the "right" motor, ESC and battery. (1) Estimate the AUW ("All-Up-Weight") of the plane; (2) Select a motor and propeller with (a) the proper thrust, and/or (b) the proper power, given the estimated AUW; (3) Determine the battery voltage compatible with the motor; (4) ...

Resistance Measurement of Busbar Welds
With the increase in battery capacity in recent years, currents flowing across busbars connecting batteries now exceeds 100 amps. In particular, high resistance values at busbar welds cause degradation of batteries due to the generation of Joule heat (RI2), potentially leading to serious accidents. As a result, management of weld resistance is becoming an even more important component of quality ...

The Hall Element Method for Current Sensing
A few months back, we posted a blog discussing the 6 different current sensing methods used in the current meters and sensors developed by Hioki. Here, we’re highlighting the sensors that incorporate a Hall Element to detect current. A Hall Element is a semiconductor sensor that applies the Hall Effect principle to measure the flow of current through a conductor via the magnetic field the ...
