ComAp MainsPro G99 Mains Protection Relay

MainsPro is a G99 protection relay for mains-to-parallel applications, including renewable energy sources such as photovoltaic plants.

It provides adjustable voltage, frequency and loss of mains protections to safeguard both the distribution network and the generators.

If you are generating power in parallel to the mains, you will need ‘loss of mains’ protection. This is essential to avoid supplying your electricity into an islanded grid, which may lead to possible equipment damage or safety issues.

KEY FEATURES:

• Unrivalled safety for installers and service engineers
• Compatibility with DNO testing procedures
• True RMS measurement for increased accuracy, reliable evaluation of failures
• Vector Shift and Rate of change of frequency (ROCOF) protections available in one unit to choose the best fit to secure your site
• Symmetrical components for better detection of voltage asymmetry failures
• Two stage settings of voltage and frequency protections to cover short term as well as long term disturbances with appropriate priority
• Free assignment of 5 relay outputs allows wide range of signaling and trip methods
• Free assignment of 4 binary switches to remotely change operation of the unit
• Adjustable time delay of Automatic fault reset which avoids necessity of on-site personnelUniversal power supply 8-40 VDC, 85-265 VAC, 110-370 VDC
• Selectable voltage range 120/230/400 VAC with over-range to 156/290/520 VAC makes the unit independent on application
• Supports 3-phase and 1-phase applications
• Last 5 trips record providing evidence of cause of trip

ComAp MainsPro G99TT (with seal)

MainsPro G99TT is a G99 compliant type tested mains protection relay for on-grid parallel-to-mains photovoltaic applications. It provides adjustable voltage, frequency and loss of mains protections to safeguard both the distribution network and the generators.

The G99 functions were added as a result of UK adopting EU Commission Regulation on harmonising network standards known as Requirements for Generators (RfG) into GB Distribution and Grid Codes.

The main change is moving from Vector to ROCOF (Rate of Change of Frequency) protection to detect how quickly the system frequency is changing by continuously sampling the frequency of mains voltage. Now ROCOF is the only approved method for Loss of Mains.

The unit has protection settings set during the manufacturing process. Some of the settings cannot be changed and some are locked in a way that only authorized personnel can change them.

KEY FEATURES:

• Easy set-up via a user-friendly interface
• Full ENA EREC G99 Type Tested compliance
• True RMS measurement
• Required for all new installations in the UK from 27 April 2019
• Wide power supply and measurement range
• Simple wiring with detachable connectors
• Remote binary communication
• Suitable for standard DIN rail installation
• Advanced frequency, voltage and loss of mains protections
• History track (last 5 events)
• Integrated mechanical lock to secure your setting
• Breaker failure protection and watchdog 
• Resistance to frequency jumps
• Two stage settings of voltage and frequency protections
• Support of 3-phase and 1-phase applications
• Voltage protection settings can be adjusted only by authorised personnel
• IP20 Protection
• 2-year warranty
