system composition

The YN-IM5000M system consists of a voltage monitoring unit and a current monitoring unit. This system adopts a distributed structure, which can be flexibly configured according to the actual on-site monitoring situation, improving the reliability and flexibility of the system.

Functional Features

→ Flexible configuration

Adopting a node based design structure, adding or reducing monitoring equipment and monitoring items does not require changing the system structure. Different types and quantities of local monitoring units can be attached to the central warning server as needed to achieve monitoring and diagnosis of different devices;

→ Easy installation

Simply install the corresponding monitoring unit under the tested electrical equipment and hang it on the bus of the monitoring device by laying a single cable;

→ Accurate measurement

Adopting high-precision and high stability zero flux current sensors, advanced digital signal analysis technology and digital communication technology are used to ensure the accuracy of phase measurement, thereby solving the accuracy and stability of parameters such as dielectric loss, capacitive current, and resistive current;

→ Reliable data

Each monitoring unit has a complete self checking function, which can timely determine the working status of the monitoring unit and upload it to the server and users. All monitoring data is transmitted through digital communication, completely eliminating signal transmission problems caused by power frequency electromagnetic interference or other high-frequency interference, and improving the reliability of the monitoring system.

simple maintenance

All monitoring units adopt a modular structure design, which has high universality and interchangeability, and can maintain all components including sensors without affecting equipment operation.

Safe and reliable

All modules are produced according to industrial standards and have good resistance to electromagnetic shock and temperature fluctuations. The device has anti-corrosion, windproof, dust-proof and other functions, suitable for outdoor high-altitude working conditions. The device adopts advanced waterproof box, fully enclosed design, and has anti electromagnetic interference function
