ENTRY AND ACCOUNTING SHIELD

Any commercial or residential building has an electricity meter at its input.

Also, if this is an enterprise, for example, a manufacturing one, then the meter is also in shops and in sections. This is necessary not only for calculations with the energy supplying organization. but also for economical consumption of energy resources, because having data on electricity consumption, you can analyze them and implement energy-saving technologies, and after their implementation, evaluate the results of such implementations.

For this, metering boards, input and metering boards are manufactured. For a faster and more economical analysis of such data, the processes of reading meter readings are automated. We implement commercial electricity metering systems (ACME). Such systems allow you to remotely receive information on electricity consumption, archive such data, as well as build energy consumption graphs, energy composition (active. reactive energy, generation-consumption, presence of harmonics, two- or three-zone).

For remote access, meters at substations are equipped with GSM modules. A wireless system can be built on the territory of enterprises. In addition to electricity metering, it is important to know its characteristics. For this, electrical network analyzers are used. Network analyzers, like electrical energy meters, differ significantly in their capabilities. They can measure from several parameters with a long time interval to a huge amount of data in a minimum time interval. Event recorders can also be installed. They can both discretely record events (switching on the machine, voltage loss, contactor switching off) and analog signals (voltage, current, frequency).

In critical production cycles, the quality of electricity must be excellent. Analyzers and recorders will help both to prevent emergency modes and to prevent them in the future.

AVR CABINETS

ATS (Automatic Backup) cabinets are manufactured according to the customer's specifications.

These can be single-phase or three-phase inputs. Both at low voltage 220 V or 380 V and at medium voltages 6-10 kV.

Cabinets can be made in a simple version, for example, when two power cables from different power sources come to the building. Each power source is equipped with an indication of the presence of phases. The electrician on duty manually switches from one power source to another. There may be a more complex version - automatic, on contactors. This case is suitable for switchboards that do not have 24-hour duty personnel. Voltage relays monitor the presence of voltage on the incoming cables (buses), and if any of the parameters on the main power supply deviate, they automatically switch to the backup power source. ATS can also be made on machines with motor drives controlled by a programmable relay.

This is a more reliable option, especially in places where the switchboards are very close to large substations. At night, there is a significant decrease in electricity consumption, and therefore there is an increase in voltage. When this is a three-phase input, the voltage from 380 V during the day can increase to 420 V at night.

REACTIVE POWER COMPENSATION

Based on the data provided by the customer: the maximum value of the consumed reactive energy, the minimum degree of growth of reactive energy, and the frequency of switching on the reactive component, the presence of harmonics in the network and their nature (we can determine this information independently on the customer's instructions) we select the necessary cabinet for the correct operation of the reactive energy compensation device.

The units can be made from imported materials or partially from domestic ones, but in any case the materials used are of well-known brands, which ensures reliable operation of the devices. The choice of parts of a particular manufacturer will depend on the operating conditions (environment, number of work shifts at the enterprise, desired trouble-free operation of the units).
