Metal Deploye Resistor recently delivered, for the national company of electricity in Qatar, Kahramaa, more than one hundred Neutral Grounding Resistors (NGR) for the project “Qatar Phase IX”.
This project required the integration of resistor monitoring systems which allow ensuring the Neutral Grounding Resistor is not damaged after a fault has happened and will be thus able to limit further defect.
All these Neutral Earthing Resistors (NER) have been fitted into substations and help to protect the electrical network of Qatar.
The protection degree of these resistor frames is IP55, which is the highest protection degree for this kind of product.
Some Neutral Earthing Resistors have passed the heating test (temperature rise test) and IP55 protection degree test with success into some external international laboratories.
To finish, the project management has been particularly critical to meet the delivery date requested by the customers.
