1. Low voltage automation and switching equipment
1.1 Does the installation of the open current adapter require a power outage?
The DP Series open type current transformer is designed for low voltage switches and automation systems where assembly flexibility is required. With its split-core structure, it allows no need to power off to install current transformers, and install directly on the Cables or buses without interruption of power supply.
As a reliable low voltage current transformer, the DP series supports two mounting options: the mounting of the base and the mounting of the bus belt, which are suitable for various switching systems. Wide internal window design can accommodate large cross-section cables, meeting the requirements of power distribution environments Density. Particularly suitable for old distribution cabinet renovation projects to avoid production losses due to power outages.
2. Natural gas measurement
2.1 Is exit 5A or 1A to be chosen for a transport distance of 200 meters?
For natural gas measurement applications, measurement accuracy and signal stability are critical. The DP series supports 1A, mA and mV output options and allows for seamless integration with throughput computers and RTUs. The main current range from 5A to 6000A covers applications from distribution stations to industrial gas users.
If the control room is more than 100 meters from the place, it is recommended to choose exit 1A. The DP series supports 1A output allocation and effectively solves the problem of signal attenuation over long distances. This open type current transformer ensures reliable signal transmission even in remote installations.
3. Marble processing
3.1 What happens if the current processors P1 and P2 are reversed?
Heavy equipment such as cutting machines, grinders and overhead cranes require robust current sensing solutions. The DP series offers high performance and high environmental tolerance and operates reliably in dusty environments with high vibrations.
The reverse polar connection can cause leakage in the measurement of three-phase wires. The DP series is clearly marked in the direction P1/P2 on the shell, allowing assembly workers to quickly identify and avoid measurement incidents due to pole errors. Its split design simplifies installation and maintenance, and deployment can be completed without interrupting production.
4. manufacturing system integration
4.1 How to choose an adapter for motor current monitoring?
With the advent of smart factories, manufacturing energy consumption monitoring CT plays an essential role in energy management systems. The DP series provides stable power signals for MES and EMS platforms and enables accurate energy tracking and predictive maintenance.
By monitoring engine current changes with the DP series, equipment faults can be detected in a timely manner to avoid engine exhaustion. For preventive maintenance scenarios, 0.5 level accuracy products are recommended to ensure current fluctuations are captured Small exactly. As a versatile open type current transformer, it provides reliable data collection across diverse manufacturing environments.
5. Technical points and selection
5.1 How to choose the conversion ratio of the current converter?
It is recommended to choose a rated current of 1.2-1.5 times the load current. It is recommended to use 100/5A or 100/1A gauges for 80A loads to avoid inaccurate measurement at small loads due to excessive selection. The DP series has a current range from 5A to 6000A and covers various industrial scenarios.
5.2 What is the difference between level 0.2 and level 0.2S?
The 0.2S level guarantees accuracy in the load range of 1%-120%, while the 0.2 level only guarantees 5%-120%. In the case of strong seasonal load fluctuations, such as in the rural power grid or in the manufacturing industry, the use of class 0.2S products is recommended. to ensure accurate measurement at low loads.
5.3 What CT size should be used for a 100 x 10 mm stem plate?
It is recommended to choose the DP-88 or DP-812 series to ensure a smooth ride and stable mounting of the bus belt. The DP series offers different interior window sizes to meet different cable and bus belt requirements.
