RT2a - VOLTAGE DIP IMMUNITY CLASSES AND APPLICATIONS
Introduction ofvoltage dip immunity labels
• Facilitate the communication and exchange of information
• Advice on what steps to take to ensure that process is not adversely affected by voltage dips
• Allow equipment manufacturers to report dip immunity of their equipment using only a few key test points

RT2a - VOLTAGE DIP IMMUNITY CLASSES AND APPLICATIONS
Classification of equipment dip immunity• 5 Classes are introduced
– Class A - highest level of equipmentimmunity
– Class B - good level of equipmentimmunity
– Class C1 - reasonable level of equipment immunity
– Class C2 - similar to class C1, take into account certain nominal voltage levels
– Class D - basic level of equipment dip immunity
Class A specification of equipment dip immunity against type I + II dips
