MEIU
MPRT EPOCH Interface Unit
ORDERING INFORMATION
DESCRIPTION
The MEIU is a small, light-weight, field portable, interface
unit specifically designed to control Multi-Amp EPOCH-II
®
and EPOCH-20 ® units with the Megger MPRT relay test
system. The combination of the MPRT and the
EPOCH-II/20 units provides a very powerful test capability.
A single EPOCH-II/20 unit can provide a maximum of 170
Amperes, at 1,000 VA/600 VA, for simulating single phase
to ground faults. With a three channel MPRT unit, the
MEIU can interface and control up to three EPOCH-II/20
units either manually from the MPRT Touch View Interface
or through the AVTS software. With three EPOCH-II/20
units, three-phase fault simulations of up to 170 amperes
per phase are possible. The combination of a three
channel MPRT, the MEIU and three EPOCH-II/20 units can
provide 6 currents for testing three-phase current
differential protection schemes.
