Zhejiang Tianpusheng Electric Co., Ltd. is one of the largest manufacturers of electric energy meters in Taizhou City, Zhejiang Province, China. One of the products we promote is 3 phase electricity meter.
When installing 3 phase electricity meter, pay attention to the following points:
1. Set up the property boundary point at the metering point. The installation place must not have corrosive gases and liquids and strong impacts around it. Choose a relatively safe place. The operating temperature of the meter should not exceed 50 degrees Celsius. Avoid direct sunlight. Extend the service life of the meter.
2. The meter installation should be installed in a dedicated meter box, and the installation height must meet the specifications. The meter installed in the meter box should not be less than 1 meter from the ground, and the meter installed in the suspended meter box should not be less than 1.8m from the ground. 3 The installation of phase electricity meter must follow this regulation.
3. The circuit between the electric energy meter and the current and voltage should be connected with a joint junction box, which can reduce the time consumed by the staff in troubleshooting.
4. The voltage and current transformers must be products with consistent specifications, the connection points must be firmly tightened to prevent power failure, the transformer must be installed in an electric meter box, and measures must be taken to prevent electricity theft.
5. Electronic meters used for remote sampling. The electronic meters for remote sampling must have a system installed to facilitate data collection. The signal wire must use shielded twisted-pair wires. When setting up the signal wire, ground the single end of the shielded wire. Improve the reliability of communication.
6. If there is a metal meter box, the meter box and the shell of the high-voltage transformer must be grounded, because the metal meter box will conduct electricity, resulting in inaccurate measurement. The grounding wire must use a copper core wire, and its wire diameter cannot be less than 2.5 square meters. Mm.
