• Measurement of the opening and closingtime delay of the main circuit-breakers
• Checking of the operating of the auxiliary circuit-breakers contacts
• Checking of the control panel and testing functionality
• Control locks
• Measurement of the resistance disconnectors contacts
• Checking of the control panel and functional testing of the disconnectors
