THE MONITORING SYSTEM FOR OVERHEAD LINES AND UNDERGROUND DISTRIBUTION NETWORKS | |
Devices: |
A3 engineers developed an integrated solution for overhead and underground lines — the distribution network monitoring system KOMORSAN. An integrated system - "KOMORSAN" is designed to promptly locate faulty sections and to transmit the corresponding data to dispatching points. The KOMORSAN system improves reliability, productivity (cost) and efficiency of distribution networking. Key faetures of the KOMORSAN system:
A3 suggests a wide variety of the device models to build up the System. The KOMORSAN system can be implemented at any type of facility with any type of network topology. |
RELAY PROTECTION AND AUTOMATION | |
Devices: |
In order to provide a reliable protection while operating with measuring circuits, signaling, control, crew safety maintenance A3 company offers technical solutions for relay protection and automation. Voltage in the network under various operating conditions must be thoroughly regulated. The voltage regulators in our UP range provide measurement, control and regulation functions for this. They can handle simple regulation tasks as well as the complex requirements of modern protection and regulation devices. A3 UP Monitors family contains a number of devices, form the very simple models suitable for solving particular problems to the complex multifunctional devices that can be employed anywhere. Using our devices one can receive position information from any type of OLTC and transmit it via digital or analog outputs. The OLTC developed by A3 has specific functionalities :
Continuous monitoring of the on-load tap-changer's operating and status conditions is essential to ensure and optimize transformer availability. We provide solutions for recording, monitoring and logging all relevant on-load tap-changer parameters to optimize the times and scopes of the service. |
RELIABLE POWER TRANSMISSION OF DIFFERENT VOLTAGE CLASSES | |
Businesses today are faced with the challenge of maintaining their network to allow for consistent availability and productivity. Therefore A3 developed and produced devices for remote monitoring and control of low, medium and high voltage classes networks, which help to reduce network maintenance costs and prevent unplanned outages:

REMOTE MONITORING AND CONTROL | |
We have developed several ways to attain control over the grid outages by a more effective and targeted coordination of the maintenance team. The ability to obtain as prompt and precise information as possible about the current state of the grid is a basic prerequisite for improving this coordination in case of a fault. The communication units are a robust pole mountable solution that works together with the Lodestar. Together they provide detailed information about fault events and actual state of distribution and sub-transmission of overhead lines. For remote data transmission from fault indicators to data acquisition server A3 designed communication units LightBox and SmartBox. |

NETWORK PARAMETERS MONITORING | |
Stop losing time. Avoid downtime and outages - save your money. Distribution network parameters visible on one screen. Compact and feature-rich A-Signal is an excellent building block for a reliable and effective smart gird. High accuracy and unique algorithms enhance the ability to locate earth faults in various types of underground, overhead and mixed networks. There is no need in specifying a type of a network grounding or selecting residual current thresholds. A-signal functionalities:
