JO-OM400B transformer local on-line monitoring system

The JO-OM400B transformer partial on-line monitoring system uses an ultra-high frequency antenna to detect and receive ultra-high frequency (UHF) signals generated by the partial discharge of the transformer to realize on-line monitoring of the partial discharge of the transformer. This system can use lE061850 protocol to output signals, and can be directly connected to the integrated online detection platform of the substation.

On-line monitoring system for transformer core/clamp grounding

The JC-OM201 transformer core/clamp grounding online monitoring system consists of the JC-OM201 transformer core/clip grounding monitoring device and the JC-8000 integrated intelligent online monitoring device. Zero-flux current transformer: The secondary side of the transformer has dual windings, and the transformers with a large range and a small range are automatically selected according to the size of the current. At the same time, it cooperates with the amplification factor of the signal amplifier circuit to achieve high-precision measurement in a wide range;

JC-OM100 Transformer Oil Chromatography Online Monitoring System

JC-OM100 Transformer Oil Chromatography Online Monitoring System (multi-component principle) is an online monitoring product for dissolved multi-component gases in transformer oil based on gas chromatography technology. The system can detect on-line the content of dissolved H2, CO, CO2, CH4, C2H2, C2H4, C2H6 and other full-component gases in the transformer oil according to the set period. The expert system can determine whether there is a latent fault, whether it is an overheating fault or Discharge fault, and alarm according to the set alarm value. The JC-OM100 transformer oil dissolved gas monitoring device can send the online monitoring information of the dissolved gas in the oil to the background software according to the IEC61850 standard through the station control layer network. The device adopts distributed control sampling technology with self-diagnosis and self-recovery functions. Each functional module has weak coupling, independent functions, and adopts a rack-mounted structure, which is convenient for project maintenance.
