First of all, we should pay attention to the following questions when selecting current transducers : whether single-phase or three-phase currents need to be detected. Current transducers usually have two forms and can be used to detect single-phase or three-phase currents.
Transmitter input current range Because of the large range of actual load current changes, in order to adapt to this situation, we usually use current transformers to convert large currents into small currents of 1A or 5A. Therefore, the current transducer input is usually selected according to the secondary current of the current transformer. For example: Current transformer secondary current is 5A, you can choose the current transducer input current is 0-5A can be.
Auxiliary power specification
The current transducer is for accurately detecting the change of the input current, and also for outputting the DC signal that changes linearly with the input current. Usually, an auxiliary power supply is the most current transducer operating power supply. In general, the most widely used is the AC 220V, which is easily available. It is also possible to select a DC power supply such as DC 24V. It should be noted that there will be some current transducers , claiming that no auxiliary power supply is required, ie a so-called "passive type" current transducer . For this current transducer , it should be carefully selected. The so-called "passive type" does not require a power supply but the meter behind the output signal of the current transformer provides the operating power. It is "eat the instrument power behind the transmitter." It naturally increases the burden on the instrument behind the transmitter. There is also a "passive type current transducer " that uses the secondary current of the current transformer as the power source of the transducer. The disadvantage of this type of transmitter is that when the load current is small, the output current of the current transformer will naturally be smaller and the energy provided to the transmitter will be reduced. At this time, the current transducer will produce Non-linearity error, thus causes the error that the electric current signal transmits, so, this kind of transmitter also needs to adopt cautiously.
Current Transmitter Input Overload Capability When the load current is overloaded, or when the system fails, the current transmitter will usually be subject to very large overload currents. In this case, it can not withstand large overload currents and become an important indicator of the performance of the current transducer .
Current Transmitter Stability
Current transmitter as a "metering instrument", in addition to the need for precision, the most important performance is the ability to work reliably and reliably. These performances are often reflected in the beginning of product design. Because of the change of the ambient temperature, any analog conversion instrument cannot avoid the temperature drift phenomenon. To reduce the temperature drift of the product, various products will adopt their own unique technologies from the aspects of components and circuits. And before the product is delivered to the customer, 100% aging test will be conducted. These contents often cannot be reflected in product sample indicators or marketing, and can only be selected by the customer based on his own experience or experience.
