NEWS & EVENTS FROM HIOKI

The Importance of Power Converter Efficiency Power converters such as transformers are widely recognized as one of the necessary components of an electrical distribution system.  Similarly, inductors such as coil, choke and reactors used as filters in power supplies play [...]

Have you ever applied a clamp ammeter around a wire only to realize that you can’t see the display?  Let's look further into viewing measured values remotely. If you try to forcibly change the orientation of the clamp ammeter because [...]

Hioki announces the launch the new SP7001/7002 Non-Contact CAN Sensor, scheduled for release in December 2019. Building upon the concept of the SP3000 Non-Contact Voltage Sensor, the new SP7001/7002 are specifically engineered to safely detect CAN-bus signals. 1.      Detect in-vehicle CAN FD [...]

    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 [...]

    In this new web series, Ask a Product Manager, HIOKI invites you to submit your product and technology questions to our Product Managers.  We’ll address them here so our whole community can benefit.   This week’s installment focuses [...]

October 6, 2019 - Nagano, Japan   Hioki is pleased to announce that its AC/DC Current Sensor CT6877, AC/DC Clamp Meter CM4375 and CM4376, and AC Clamp Meter CM4141 and CM4142 have been recognized with 2019 Good Design Awards by [...]

Calibration is like a health checkup for your instrument Because it verifies the condition of an instrument, calibration is like a health check.  Specifically, Hioki calibration services involve confirming the condition of an instrument at a particular point in time [...]

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 [...]

  Fault Ride-Through (FRT) To ensure critical equipment continues to be up and running despite power quality problems such as voltage dips, companies must make sure that adequate fault ride-through capability is included when the equipment is purchased.  Customers then [...]

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 [...]

Electricity theft - the crime that nobody talks about - is often an “invisible” crime. Someone illegally taps into a power supply, hooks up a line that has been disconnected, or tampers with a meter to avoid recording electricity usage. [...]

  Join us for Introduction to Current Sensing Methods and Techniques on Aug 14, 2019 at 3:00 PM EDT.  Register Now!   Depending on the circuit characteristics and the amount of AC or DC current that is expected, engineers have [...]

The accuracy and tolerance described in the product specifications for many Hioki measuring instruments are given in terms of rdg., f.s., and dgt. Measurement uncertainty is often defined, and the uncertainty limit is obtained from the extent of these values, but [...]

         6 Current Sensing Methods 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 The [...]

What is a Resolver?   A resolver is a rotary transformer consisting of a sensor that is used to accurately measure a rotor's angular position relative to the stator, as well as speed of rotation.  It has no electronic parts, which [...]

Join us for a webinar on Jul 30, 2019 at 3:00 PM PDT (6 PM EDT).   Register now!   RGB lasers are forecast to take over as the predominant light source for displays in the future in products like [...]

Let's explore Power Quality Analysis Tools for Effective Risk Management.  As we all are aware, energy is neither created or destroyed, it simply undergoes transformation from one type of energy to another. In today’s world of diverse energy sources electrical [...]

Hioki is consistently striving to excel.  It’s evident in our technologies, our products and, of course, in our customer service.  We work hard to provide our customers with a level of customer service they won’t find from other manufacturers.  It’s important [...]

Impedance is a form of resistance that is necessary to resist and react to the flow of current in an AC circuit. Unlike resistors, which when used alone to manage the current flowing through a DC-powered circuit is rather straightforward, components in [...]
