TS7 Off-Grid Testing Benefits • No grid restrictions … no frequency or load

limitations

• Testing at all load ranges on-frequency (50 and 60hz capable)

• Testing at load ranges off-frequency for variation and grid events

• Testing at transient conditions

• Deliver thorough product mapping beyond field operation … insurer and customer acceptance

• TS7 has permanent data collection system

• Capable of 7000 data streams

• High quality data due to permanent data and scanner rooms.

FSFL provides data far beyond field operation
