5. Hardware requirements

Technical means ACSEE SS should be sufficient to perform all functions of the system with the appropriate characteristics, highlighted in these specifications.

As the technical means should be used ACSEE SS uniform technical means of mass production. If necessary, allowed to use separate hardware unit production.

Each of the hardware ACSEE SS should allow its replacement by means of the same functionality without structural changes in the regulatory or other technical means ACSEE SS (except specially stipulated in the operational documentation to ACSEE).

The hardware must include equipment to connect to the server and AWP LAN.

1. Requirements for the counters of electric power

To measure the power and presentation of the results of measurements should be used multifunctional electronic electricity meters of accuracy class 0,2S, 1 (2) A.

Interfaces counters must be protected against overloads using special protective devices.

The ACSEE should be implemented redundancy of information channels of communication with meters, for which electricity meters must be equipped with two independent interfaces.

Cable news channel of communication should be routed separately from the current-carrying conductor along the shortest path.

It must be provided for mounting the cable news channel in the vicinity of the attachment.

2. The requirements for communication cabinet acsee ss

Cabinet Communications ACSEE SS is designed for equipment that performs the functions of receiving, storing and processing information, which comes from the electricity meters.

The cabinet must be installed on the floor and equipped with a fan unit with thermostat.

The cabinet must be capable of placing the server and communication equipment ACSEE and have space to accommodate additional or backup equipment in the amount of not less than 30% of the total.

The cabinet must be installed in the room where the equipment will be located server ACS substation. No direct exposure to sunlight on the cabinet and its installation near the heating system (the distance from the heating system is not less than 1 m.)

Communication equipment ACSEE, which is placed in the cabinet, with the electricity meters should be cable type 5e SFTP.

Cables of information channels, which are routed to the cabinet must have a reserve of length 2 m for installation inside the cabinet and processing all conductors.

Features server hardware:

• As server should be used industrial computers increased reliability c possibility of creating RAID- array. As part of the server must have two power supply and at least two network cards. Hard disk drives and power supplies must support the ability to "hot swap" function (Hot swap). We recommend using a server with extended operating temperature range (greater than 25 ° C.) For the premises where they will be used.

• construction of servers must allow their placement in special racks, cabinets floor mounting;

• the server must be designed for continuous operation. Disable the server is allowed during routine maintenance;

• general and application server software must allow the simultaneous operation of all communication ports.
