? All in one:
The system is an organic combination of multiple logic devices. With a modular design and excellent extensibility, the user can freely and flexibly configure the number of channels for data collection. Simple but reliable, the system helps save on costs for purchase, management, and maintenance.
? Expert analysis system:
An expert analysis system is built, including an oil-gas analysis mathematical model (IEC 60599-compliant) and a heat management mathematical model (IEC 60076-7-compliant). Through the relevant data on oil-gas monitoring and temperature management, the system can conduct an initial analysis, diagnostics, and early warning of a transformer fault.
? Load management analysis:
The system monitors in real time load rates, judges the overloads in the transformer, and provides a corresponding load-shedding solution in order to improve its operational safety and cost-efficiency.
? Abundant I/O interfaces and extensibility:
The system can be maximally configured with two analog receiving cards (0-10v, 2×32 channels), one switch receiving card (32 channels), three switch output cards (double paths, idle contact, 3×24 channels), two extension cards (0-20mA, 2×8 channels). The numbers of I/O cards and extension cards are decided by the contents of user monitoring.
? Association analysis:
Further association analysis is made of the data collected from various functional modules and analytical results for mutual support, improving the correctness and consistency of diagnostic results.
? IEC 61850 standard:
The system supports multiple communication methods such as IEC61850, 103, and RS485. Modeled in line with the IEC 61850 requirements, it is interoperable with other smart devices and can be integrated with other intelligent systems for data sharing.
? Real-time online monitoring:
Online monitoring is adopted to reduce the routine work of grid management personnel, avoid repetitive work, reduce workloads, improve productivity, and reduce operations & maintenance costs.
