CAT NO: DIDACTICECE-LAB-0102
Set of protection relays for high-voltage and low.
TRAINING PROGRAM:
• Connections and study of the behaviour of a maximum current
relay in a three-phase network with different current values, verification of trip time.
• Connections and study of the behaviour of a short-circuit
current relay in a three-phase network with different current
values, verification of trip time.
• Connections and study of the behaviour of a single-phase
maximum or minimum current relay,
verification of trip time
for maximum and minimum current.
• Connections and study of the behaviour of a maximum or
minimum DC relay, verification of trip time for maximum and minimum current.
• Connections and study of the behaviour of a maximum
and minimum voltage relay in a three-phase network with
neutral, verification of trip time for maximum and minimum voltage.
• Connections and study of the behaviour of a single-phase
maximum or minimum voltage relay,
verification of trip time
for maximum and minimum voltage.
• Connections and study of the behaviour of a maximum
and minimum DC voltage relay, verification of trip time for
maximum and minimum voltage.
• Connections and study of the behaviour of a maximum and
minimum frequency relay, verification of its operation at
maximum and minimum voltage.
• Connections and study of the behaviour of a phase
sequence and voltage asymmetry relay in a three-phase
network, verification of its operation with wrong sequence
and in non-asymmetric conditions or missing phase.
• Connections and study of the behaviour of a maximum
current directional relay in a three-phase network,
verification of its operation with reverse current fl ow and
as directional of maximum earth current (suitable for lines
and generators).
Accessories supplied:
