Services

We design each system around the facility load profile, grid connection conditions and intended energy use. Battery modules, power conversion, protection, distribution and supervision are integrated into one technical system.

Technical system

Our scope includes battery modules with a battery management system, AC/DC inverters, LV switchgear, cabling, protection devices and technical or containerised enclosures. System ratings and architecture are selected for the facility operating conditions.

Integration and commissioning

We integrate battery storage with photovoltaic generation, local metering, energy management systems and building automation. Communication interfaces are configured before commissioning, technical documentation and operator training.

We integrate electrical equipment, building automation and telecontrol using the power-system architecture, signal list and technical documentation requirements. Metering, control and communications are combined into one system.

Telecontrol and data exchange

We deliver telecontrol systems, integrate equipment with SCADA and implement Modbus communications. Our work covers signal transmission, parameter visualisation, remote monitoring and control.

System commissioning

Once the equipment is connected, we configure control dependencies and verify communications and data logging. Commissioning concludes with functional testing under the facility operating conditions.

We test new and modernised MV cable circuits before they are put into service. Voltage testing, insulation measurements and sheath integrity tests verify installation quality and provide the records required for technical acceptance.

When testing is required

Testing is carried out after construction or modernisation and before the circuit is energised. The method is selected according to cable type, rated voltage, accessories and acceptance criteria.

Test scope

• visual inspection of the cable circuit and accessories
• continuity checks for conductors and return paths
• conductor resistance and insulation resistance measurements
• VLF withstand testing
• DC cable sheath integrity testing and leakage-current measurement

VLF test procedure

The test section is identified, isolated and made safe before the test equipment is connected. The test sequence is recorded, after which the cable is discharged and earthed.

Cables covered

The test scope for an MV cable circuit is established from its rated voltage, cable construction, accessories and handover documentation requirements.

Test documentation

The report identifies the tested section, method, test sequence and results required for the technical acceptance records.

Test equipment

Equipment is selected for the test type, rated voltage and cable construction. Results are recorded in the final test report.

We design and construct power supply infrastructure, from cable lines and grid connections to switchgear, protection, earthing, testing and commissioning. Our work covers new systems and the diversion of networks that conflict with a project.

Design and approvals

We prepare designs and coordinate the required approvals with grid operators and other project parties. Construction is based on approved documentation, grid connection conditions and discipline-specific agreements.

Networks and facility power supplies

Our scope includes overhead and cable LV/MV lines, grid connections, MV/LV transformer substations and temporary or permanent supplies for facilities and process equipment.

Technical acceptance

After construction, we verify circuit continuity, connections, protective systems and acceptance parameters. We prepare as-built documentation, complete the required measurements and make the installation ready for energisation.

We combine photovoltaic generation with grid connection infrastructure, protection, metering and battery storage. The use of generated energy is configured for the facility load profile and technical conditions.

Installation scope

Works cover support structures, PV modules, DC and AC systems, inverters, power distribution, protection and metering. All elements are integrated with the facility electrical system.

Battery storage integration

For hybrid systems, we integrate PV generation with battery storage and an energy management system. Energy flows, communications, monitoring and equipment interaction are configured for the facility.

We deliver control systems for road and transport infrastructure, integrating controllers, detection equipment, signals, data transmission and central supervision.

Field equipment and control

We install power and control connections for controllers, signals, detection and monitoring equipment and data transmission devices. System functions and data exchange are then configured.

System commissioning

After installation, connections, communications and operating scenarios are verified. The system is handed over following functional testing and completion of as-built documentation.

We deliver lighting systems that require coordinated luminaires, power supplies, control, support structures, testing and commissioning. Applications include public spaces, roads, sports facilities and aviation infrastructure.

Power supply and control

We construct cable lines, columns and high masts, and install luminaires, lighting control cabinets, protection and time-based or functional controls. Specialist systems are integrated with the facility operating infrastructure.

Modernisation and new systems

For existing infrastructure, we assess power supplies and control components before replacing luminaires. New systems are delivered with their supply, controls, measurements and handover documentation.

We deliver projects in which electrical power and technical installations form part of a larger building, road or municipal infrastructure scope. Responsibilities and the sequence of work across all disciplines are coordinated within one delivery process.

Multidisciplinary coordination

Building and earthworks are coordinated with electrical, sanitary, ICT and automation systems and external works. We manage interfaces between disciplines and the acceptance of individual installations.

Delivery model

AGZ works as a general contractor or specialist contractor. We are responsible for the documentation, supplies, construction, commissioning and handover included in the contract.
