The device has powerful integration and expansion capacities. It not only satisfies the functional requirements of the current distribution network automation, but also provides sufficient expansion space for further improvement and upgrading. It boasts of the following features

Reliable and Stable Operation

The device inherits the rich R&D and onsite operation experience of our company in relay protection devices, measuring and control devices, communication devices and distribution network automation. Many relevant aspects are taken into account and various technical methods are adopted. The terrible operating conditions for the device are fully taken into account in the design. The device features excellent electromagnetic compatibility, low power consumption and a wide range of operating temperature. It is shockproof, moisture-proof, lightning-proof and of great reliability and stability.

>Atmospheric pressure: 66kPa～108kPa.

Operating environment: no explosive and flammable materials, no air or conductive dust which will damage the insulation and cause metal corrosion, no serious mold and no severe vibration sources, with measures to defend against rain, snow, wind, sand, dust and static electricity.

Adequate and Practical Functions

It boasts of all the functions required for the present relay protection and can carry out on/off combination according to the practical requirements. It can fulfill the “four-remote” (remote signaling, remote metering, remote control and remote regulating) functions through the local serial ports and realize the remote communication function by different optional communication modes.

Operating ambient temperature: From -40℃ to +85℃.

Relative air humidity: The air humidity can not exceed 50% at the maximum temperature and higher air humidity is allowed at lower temperature. For example, the air humidity shall be 90% at +20℃ as it may occasionally cause condensation with the temperature changes.

There are three toggle switches on the panel of the device. The function definition varies as different switches are used. The configuration schemes of toggle switch are as follows:
