Trench China
Line Trap
Trench China
is pleased to announce that it has passed a record short circuit test
on one of its highest rated Line Traps.
The Line Trap rating is 3150A, 1.0mH with a short circuit capability of
63kA/2sec and a mechanical peak of 161kA.
The test was conducted at the highest limit of the power supply of KEMA's
short circuit test facility in the Netherlands. |
500kV
Air Core Dry type Reactors for Bus Tie Application
TUCURUÍ BRAZIL PROJECT….550 kV System
|
| Trench
has successfully tested one of the largest air core dry type reactors ever
built. Trench is the turnkey contractor to Eletronorte (Brazil) for the
supply, installation and commissioning of a complete bus tie reactor system
including the TRV capacitors. Commissioning of the reactors is expected
to be completed by April 30, 2003.

| The
Tucuruí hydro power project, totaling 8,490MW, is located on the
Tocantius River in the northern state of Pará, in Brazil. It consists
of two independent power houses built in one dam. |
| Construction
started in 1975 |
Stage
1:
First generator went on line in 1983.
Stage 1, now fully operational, has 12 generators of 350MW each, for a total
installed capacity of 4,200MW.
Stage 2:
Presently under construction, will have 11 generators @390MW each, for a
total installed capacity of 4,280MW.
The first machine of Stage 2 went on line in 2002 and a new generator is
expected to go on line at 4 month intervals. |
Tucuruí
Dam |
The
total project is scheduled for completion in 2006.
Application: Bus Tie Reactor between stages 1 and 2
Reason: Short circuit rating for equipment in stage 1(40kA),
would have been exceeded if stage 1 was to be inter-
connected with stage 2 directly.
Reactor Ratings: 20 ohms, 2600 Amp
Power Rating 135 MVA/phase
1550 KV BIL |
