Equipment Specification

2. Existing on-site accounting.

At present, the electricity metering at the facility is organized according to the following consumer groups:

2.1 Accounting of electric power consumption by household appliances is carried out by single-phase electric power meters installed in introductory distribution boards on staircase floors or directly in apartments.

Electricity consumption by electrical appliances of legal entities is recorded by three-phase and single-phase meters located in the premises of legal entities.

2.2 Accounting of electric power consumption for technical purposes (elevator equipment) is carried out by three-phase electric energy meters installed in GRL.

2.3 Accounting of electricity consumption for the needs of public lighting is carried out by three-phase meters installed in GRF.

Existing meters can be included in the designed PAM AIIS if the conditions of Section 3 of TRP201110KS.PZ.

Installation Instructions

To mount counters of the electric power in a case it agrees with the scheme TRP201110KS1.ShU. To install cases of account and the equipment of communication in rooms of GRShch1 and GRShch2 according to the plan of placement of the equipment TRP201110KS1.S0.

Current transformers shall be installed in the cell of group connections:

- Transformers of current of GRShch1, Input 1, Input 2 to mount in the top section on combined tires, after FU1 and FU2 safety locks. The transformers shall be attached to the textolite site, which shall be installed on site. Current transformers shall be installed in three phases.

- Transformers of current of GRShch2 of Input 1, Input 2 to mount in the top section on combined tires, after FU1 and FU2 safety locks. The transformers shall be attached to the textolite site, which shall be installed on site. Current transformers shall be installed in three phases.

Voltage current measuring circuits shall be made with NYM 4x2.5 cable. Connect the cable wires to the busbars leaving the lead-in disconnectors in RG1, RG2 and the test terminal block in the metering cabinet according to the connection diagram TP201110KS1.E3

Current measuring circuits shall be made with NYM 4x2.5 cable. Connect the cable wires to the current transformers at the inputs of RG1, RG2 and the test terminal block in the metering cabinet according to the diagram TP201110KS1.E3.
