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 [...]

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 [...]

Calculate a Resolver's Angle of Rotation

By |2019-07-23T19:11:25+00:00July 19, 2019|Categories: Uncategorized|

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 makes it suitable for long-term use in harsh and demanding environments including those with high temperatures, [...]

Power Quality Analysis Tools for Effective Risk Management: From Generation to Distribution

By |2019-06-27T18:12:07+00:00June 18, 2019|Categories: Uncategorized|

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 energy has clearly gained in popularity among alternatives because of its minimal impact to the environment. However, when we look at the different sources of energy [...]

LCR and Impedance Meters

By |2019-05-31T17:31:03+00:00May 31, 2019|Categories: Uncategorized|

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 AC-powered electronics such as conductors and inductors manage the flow of current based on the operating [...]
