In order to investigate the insulation analysis of the oil-paper insulation system, the polarization current is measured using an electrometer technique. Figure 2a illustrates the PDC measurement approach employed for the OPI sample, utilizing a direct current (DC) excitation voltage of 1000 V. ...
Electric current is the flow of electric charge and is measured with an ammeter. The SI unit for measuring electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second. While there are several methods of measuring current, the most common method is ...
Essentially, a high current is transformed into a lower one using a magnetic carrier, thus very high currents can be measured safely and efficiently. In most CTs, the primary winding has very few turns, while the secondary winding has many more turns. This ratio of turns between the primary...
The Current Sensor block represents an ideal current sensor, that is, a device that converts current measured in any electrical branch into a physical signal proportional to the current.
CompactRIO is a programmable control and monitoring system with a multi-core processor, real-time operating system, programmable FPGA, and compatibility with all C Series modules from NI and 3rd party companies. CompactRIO lets domain experts build embedded I/O controllers and monitoring systems to ...
Evaluation of glomerular filtration rate (GFR) is central to the assessment of kidney function in medical practice, research and public health. Measured GFR (mGFR) remains the reference standard, but the past 20 years have seen major advances in estimated GFR (eGFR). Both eGFR and mGFR are ...
On the other hand, flexibility contradicts with the certainty in the estimates and this uncertainty is measured by a higher value of variance error. However, a model with low order yields to greater system computational errors, referred to as bias errors. Therefore, it is required to maintain ...
The current ratio is most useful when measured over time, compared against a competitor, or compared against a benchmark. Another drawback of using the current ratio involves its lack of specificity. Unlike many other liquidity ratios, it incorporates all of a company’s current assets, even th...
As an important zone for wave-ice interactions, the marginal ice zone (MIZ) is defined as the transitional zone between the ice-covered sea and the open ocean (Dumont et al., 2011). MIZ widths, which were measured by its ice concentrations from the satellite observations (Strong and Rigor...
Voltage is measured across the terminals of the power source (just as measuring the height of the overhead tank). Current is measured inside the circuit (similar to measuring water with a flow meter). Current is measured using an ammeter, which is included in a multimeter. ...
