Network based Three (3) Phase Monitoring and Control Device



Three-phase electricity monitoring and control is the most important factor to consider in electric power distribution networks and more especially for industrial electric motors and machines that works only with three phase lines. If any of the three phase line fails, the three phase motor winding will draw more current than the other and excess heat will be generated causing deterioration of the motor insulation. This can permanently damage the motor due to phase failure. Phase failure and unbalanced voltage can damage electric motors. They are the two important problems that always effect smooth running of three phase motors after installation. Phase failure can be said to occur when any of the three phase line is being cut off, while unbalanced voltage is when there is a critical over voltage or under voltage in the three phase lines. It is a very big risky for electric motors when they continue to operate in these conditions.
In some cases, overload and phase failure relays are used to protect three phase motors from these ugly situations, by disconnecting the motor from the power line but some components use in this techniques cannot perform fast switching.
Another area where the detection and monitoring of three phase power lines are very necessary is the utility power distribution transformers and poles. When there are problems in street transformers or electric poles which lead to phase failure, people usually accuse the power distribution company and start to change their loads from one phase to another and at the same time overloading the available phase.
ADACC Network based Three Phase Monitoring and Control device can effectively monitor the three phase line and notify the Utility Power Authority of phase imbalance or failure in electric poles or transformers. The device can perform the following:
1.     It assists the power distribution companies to maintain and deliver quality service to their consumers.
2.     If implemented in machines, the system will turn off power to machine during the above mentioned power problems.
3.     It will increase motor life.
4.     It will help to reduce maintenance cost of three phase motors and the risk of electric shock or fire due to the over stressed motor winding.
5.     It can be used for power line cable vandalism detector system

This device can monitor the transformer temperature and oil level or other abnormal conditions. 
Engineers are challenged to utilize this concept in different applications to make the world a better place to live. feel free to contact us: Able Designs and Construction Company. abledesigns@yahoo.com. +234-8037909203.
