Manta Test Systems in partnership with Virelec
Ltd., automated the factory acceptance testing of protection and
control systems in the Transelec’s Charrua transmission project.
This was part of a $US86 million turnkey series capacitor system
(SCS) contract with Transelec, the main Chilean transmission operator,
to strengthen its transmission grid secured by a consortium led by
Alstom. The automated testing was critical to being able meet
Transelec’s aggressive time schedule. Manta’s MPower software
allowed for completion of the required testing in a fraction of the
time and effort that would have been required by manual testing.

The consortium, which includes Mitsubishi, GE and Virelec,
will supply a full turnkey solution to transmit electricity produced by
the RALCO 570 MW hydro-power plant within central Chile.
The scope of the entire project includes the construction of
four 500 kV SCS, a new 500kV / 220 kV substation at Charrua, the
expansion of two 500 kV substations at Ancoa and Alto Jahuel,
the supply of 1,500 MVA autotransformers, 500 kV reactors, a
digital protection and control system and all related civil works,
erection, testing and commissioning.
By using SCS technology, Transelec can increase the transfer
capacity of its 500 kV system, thereby avoiding the costly and
time-consuming process of building new transmission lines. The entire
infrastructure is expected to be in operation by mid-2004.
