Measurement transformers are devices used to increase or decrease the voltage and current intensity of an electrical circuit.<\/span><\/p>\n

The values of the output voltage and current intensity, i.e. at the measurement transformer’s output, will therefore be different from those of the input current, while the frequency and waveform will remain unchanged, thus allowing high currents to be measured with normal tools.<\/span><\/span><\/p>\n

Current transformers are essential components for low and voltage energy monitoring as they adapt the signalling from the primary source, converting it so that it is available to energy monitoring products.<\/p>\n

Thanks to their precision and ease of installation, current transformers can be matched from simple energy meters all the way up to meters.<\/p>\n

All current transformers (CTs) comply with current standards and their purpose is to reduce primary current values by matching metering or protection equipment, providing a reduced secondary current proportional to standard values.<\/p>\n

A voltage transformer makes it possible to change the voltage and current values of an AC power source while maintaining the same frequency.<\/p>\n

The output voltage is constant and is directly proportional to the number of metal coils winding the conductors.<\/p>\n

Voltage transformers can therefore provide a wider output voltage range, being able to directly select how many volts to supply the device with.<\/p>\n

The purpose of the shunt is to allow the passage of current<\/p>\n

exceeding the capacity of the tool. The latter will therefore only be traversed<\/p>\n

only by a current corresponding to its capacity, avoiding the dangers<\/p>\n

of damage to the measuring equipment.<\/p>\n

Shunts are resistors of very small value and for this reason are sometimes made up of busbars of limited length and large rectangular cross-section.<\/p>\n

To aid heat dissipation, several busbars are sometimes made in parallel, terminating in two terminals with a large contact surface area. Next to the two current terminals and in connection with them, there are two further terminals which serve to connect the ammeter.<\/p>\n

These terminals have a smaller cross-section because the current required for the reading tool is much lower than that of the shunt. In fact, rather than the shunt being in parellel to the tool, it is the tool that is shunted to the terminals of the shunt, of which it utilises the voltage drop, taking a part of the circuit current, proportional to the total current.<\/p>\n
