Section 5: Ground Fault Indication (If Equipped)

Introduction

This section describes the Ground Fault Indication (GFI)
feature. To enable this feature, contact an IASD.
Power Zone 410 generators have CTs on all phases to
provide phase current measurements. This data is used
to calculate system current, powers, and power factor
(PF). The new feature of indicating large ground fault cur-
rents will use data from the existing CTs to compute the
current going to both ground and neutral. This value will
be compared to the customer-defined threshold and will
indicate when threshold is exceeded for a customer-de-
fined delay time.

Requirements

• GFI function is an optional function and needs to be
ordered with the system requirement.
• ONLY available to three-phase units.
