Thermitest
THW-L2
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.

Tap Changer Analyzers & Winding Ohmmeters
Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints

Digital Ior Leakage Current Clamp Tester
MCL-400IR+
MULTI MEASURING INSTRUMENTS Co., Ltd.
・About Ior Leakage CurrentRecently, the leakage current clamp meter is widely used for insulation control of low voltage circuit as the supplementary method of the insulation resistance measurement. The control of leakage current has the advantages to enable the prediction of insulation condition in the electrical power line without having to shut off the power. The leakage current (Io) includes the capacitive leakage current (Ioc)originated in the capacitance and the resistive leakage current (Ior) originated in the insulation resistance each related to the ground. It is considered that the measurement of resistive leakage current (Ior) is the very useful and effective method for the insulation control of low voltage circuit. However, it was difficult to measure the resistive leakage current (Ior)with traditional leakage current clamp meter. MCL-400IR new digital clamp tester enabled the measurements of the resistive leakage current (Ior)without voltage input(phase detection).
