Special components for the DC feeding systems ensure faultless emergency shutdown to avoid severe damages to the system and possible injury of people. Preventing unnecessary disruptions to operation with accurate fault detection has a considerable impact on rail traffic and availability of the system.
Many DC electrical measurement products manufactured by Knick contain universal, also known as broad-range, power supplies. This means that they will work over a relatively large voltage window, for example 20…253 V, AC or DC.
Voltage and current transducers from Knick bring true control to electrical measurement applications across a wide-range of industries. With a number of solutions engineered for measurement and safe isolation of DC voltages upwards of 4800 V, and other transducers that offer precise conversion of AC voltage inputs to standard DC outputs, Knick truly is a problem solver from 480 to 4800 volts.
Transformers have long been considered important components within electrical systems. When a need arises to step voltage in a circuit either up or down for purposes of power transmission or distribution, there is no doubt that these devices are essential.
As electrification becomes more prevalent across many different classes and types of vehicles, the technology that drives its backbone of systems and components continues to advance. This is especially true with batteries, where gains in efficiency, size, charge time, and capacity seem to be ever moving.
Applications for DC electrical transducers are encountered often within the rail industry for measurement purposes. They are prevalent on both rolling stock and substation equipment dedicated to traction power. Information afforded by voltage and current measurements is often used for control, safety, and data collection.
Critical electrical measurement applications found within the rail transit industry require equipment that can keep up with the demands seen. Safety, precision, speed, and ease of use, are all important factors to consider when making component selection. Depending on the application, different factors might weigh heavier than others.
There are many systems where measurement of large DC currents are needed for performance and safety. Two examples are static excitation and rail traction power. These current measurements are often made by one of two main principles: shunt resistor with mV transducer or Hall effect feed-through sensor.
The reliable detection of short circuits and the proper handling of signal transmissions is not only important for smooth rail operations, but also for the safety of employees and passengers. Precision and reliability with voltage and current measurement, in addition to sound signal separation and conversion, are critical in ensuring this safety on both rail vehicles and in substations.
Failure of equipment on the plant floor can lead to considerable and costly disruption. For operators of power generation facilities, transport systems, chemical, pharmaceutical and other production plants, a continuous and reliable operation is of the utmost importance. Failures of components can put a halt to important processes, costing both money and time. Devices which rarely fail are critical to maximizing a plant’s uptime.
