Split Core CT
Low Voltage CT
Medium Voltage CT
Iron Cores Series
The electrical fire monitoring system is mainly composed of the electrical fire monitoring system host, electrical fire detector and split core residual ct. Mainly used to monitor the residual current in the circuit system, so as to determine whether there is a danger, and timely warning.
1)Indoor current transformer，current transformer for energy meter.
3)Sizes of inner hole , it is 25mm,45mm, 65mm,80mm,100mm,150mm
Zhikai ,we own one strong R&D and QC team continues to innovate new solutions for customers in the area of Smart Grid Industry all covering distribution, Saving&Protecting&Metering Electicty, and Power System.
Note: The current Ratio above are common type, other specifications can be provided according to customers requirements
Electric fire monitoring system in the TT system of method of use: l
Residual current transformer is best set in the upper air switch into the line, and avoid in the future when using the bottom line is not standard cause false alarms.l A, B, C, N four cables must be direction at the same time through the residual current transformer, PE line shall not be through the transformer.l distribution box for N lines are strictly prohibited from any PE line overlap or repeat grounding, not in front of the residual current transformer lap N line after the residual current transformer circuit must be independent, may and protection areas other than the line distribution box with zero or any electrical connections.
