Safety testing device for Cable Insulation strength
Intelligent on-line monitoring device of cable insulation strength can analyze the health status of cable through the electrical characteristics of cable working. By adding the detection signal, the insulation degree and working temperature of the cable can be effectively identified, and the classical values can be compared and analyzed. It can effectively identify the aging and overheating phenomena of cables and their joints. Early prediction of cable operation failure provides a strong guarantee for the safe operation of field equipment. At the same time, the system is also a maintenance system for cable equipment failure prediction. It can send out alarms and inspection proposals before cable equipment failure to ensure the safety of enterprise production.
- The three-phase insulation resistance is monitored in real time without power outage measurement, and the results are
- Through the injection of the detection signal, the insulation degree and working temperature of the cable are effectively
identified, and the classical values are compared and analyzed.
- Effectively identify the aging and overheating of the cable and its joints, predict the cable operation fault in the early stage,
and provide a powerful guarantee for the safe operation of the field equipment.
- It is a predictive maintenance system for cable equipment failure, which can send alarm and maintenance suggestions
before cable equipment failure to ensure the safety of enterprise production.
The device can be used in any scene with electrified cable, such as power cable,
communication cable, coaxial wire and cable, ship vehicle wire and cable, data signal
cable, mining cable, optical fiber cable and so on.
- The low frequency signal injection method of real time on-line monitoring of the insulation strength of the power supply line to the ground can still monitor the insulation strength of the power system to the ground through the external sampling module when the bus is open;
- which can be applied to the 11500VAC system.;
- 2 alarm threshold provides two dry contact outputs, one RS485 communication interface, standard MODBUS-RTU communication protocol
