Calibration: Indispensable for Ensuring Continuous Use

By |2019-09-17T19:14:05+00:00September 17, 2019|Categories: Uncategorized|

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 by comparing the ideal value indicated by a standard and the value indicated by the instrument [...]

Verifying the Electrical Potential of Large Equipment

By |2019-09-05T19:48:09+00:00September 5, 2019|Categories: Uncategorized|

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 electrical [...]

Verify Fault Ride-Through (FRT) Capabilities in Equipment and PV Systems

By |2019-08-26T19:29:30+00:00August 26, 2019|Categories: Uncategorized|

  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 use the fault right-through or FRT capability curves that manufacturers provide so that they can properly [...]

Resistance Measurement of Busbar Welds

By |2019-08-23T17:55:14+00:00August 23, 2019|Categories: Uncategorized|

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 [...]

Electricity Theft: The crime that nobody talks about

By |2019-08-16T19:35:46+00:00August 16, 2019|Categories: Uncategorized|

Electricity theft 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. For example, some people will reverse their meters so they run backwards, others with crack the meter seal open and place mechanical brakes to [...]

This webinar addresses the most popular current measurement techniques, and [...]

Understanding Accuracy Specifications

By |2019-07-26T16:14:56+00:00July 26, 2019|Categories: Uncategorized|

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 we have found that many customers are not familiar with the terms.  Let's take this opportunity [...]

The Hall Element Method for Current Sensing

By |2019-07-24T20:05:27+00:00July 24, 2019|Categories: Uncategorized|

         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 sensors that incorporate a Hall Element to detect current. A Hall Element is a semiconductor sensor that applies [...]
