ITEM DESCRIPTION:
1 unit Transmission Line Simulator includes
Power Factor Load Bank
Learning Outcomes Single-phase line:
-c Short-line investigation
-c Medium or long-line investigation (nominal
-˜Tee- and -˜Pi- methods)
-c Effect of power and reactive power flow on
voltage drop and transmission angle
-c Medium/long-line investigation of a natural
load of a line
-c Voltage regulation at constant load and
power factor
Three-phase lines:
-c Per-unit values
-c Unbalanced loads and the neutral connection
-c Fault simulation and line protection studies
-c Parallel feeders and multi-section lines
-c Parallel feeders and multi-section lines
Key Features:
-c Fault application switch and earth fault
resistors allow studies of earth fault currents
and the operation of relays of varying
sensitivity
-c Enables -˜Pi- or -˜Tee- methods of loss profiling
-c Single and three-phase lines for separate
tests
-c Built-in industrial-standard digital protection
relay gives wide range of functions - module
includes extra socket for additional relay to
give more experiments
-c Includes supplies, circuit protection, internal
load banks, instruments and controls
Key Specifications
-c Single-phase and three-phase lines
-c Six-section three-phase line
-c Resistive, inductive and capacitive loads
-c Overcurrent protection relay
The console is divided into two panels, each
with detailed mimic diagrams. The upper
panel has a single phase transmission line
equivalent circuit, and the lower panel a three-
phase transmission line. The lines may be
loaded by the resistive, capacitative and
inductive loads included. The effects can be
monitored by instruments at the send and
receive ends of the transmission lines
The single-phase transmission line includes a
set of inductive impedances connected in
series. Tapping points allow the user to:
-c change the length of the simulated line;
-c set up `Pi` or `Tee` methods of loss profiling
using different values of capacitance; and
-c monitor the voltage, current and power at
any point along the line
The three-phase transmission line is in six
sections represented in `per-unit` values.
Facilities include:
-c Operating under variable balanced or
unbalanced RLC (resistive, inductive and
capacitative) loads
-c Selectable neutral
-c Provision to vary the length parameters
A fault application switch and earth fault
resistors allow studies of earth fault currents
and the operation of relays of varying
sensitivity.
For protection tests, current transformers (CTs)
in the test circuits connect to the protection
relay fitted to the control panel.
The user connects and sets the protection relay
to detect line and eareth currents. The relay
also monitors and measures fault events and
disturbances for fault analysis. The user sets
the relay from its local control panel or by a
cable link to a suitable computer and software
(included). When a circuit fault happens, the
relay opens circuit-breakers in the test circuits.
The circuit breakers also include hand-operated
switches, and lamps. The lamps show whether
the circuit-breakers are open or closed.
Line simulation: Inductors, with three-phase
line represented in per-unit values
Three-phase lines: Five sections, each at...
