Disconnect test terminal against induced high voltage
Measures to minimize risks of electric vol-
tage peaks in control systems of power
plants and transforming stations:
• Insulation between installation and con-
trol cable by pulling disconnect plugs.
• Grounding of control cable is possible on
an appropriate location of the workplace.
• Easy connection of electric isolation of
counting, control and communication cir-
cuits.
Electricity Supply Industry Standard
ESI 12-4 1973
The Electricity Supply Industry Standard
ESI 12-4 1973 defines a detailed specifica-
tion of control and protection equipment.
The main functions of thiese installations
are as follows:
• Insulation of the control cables located in
front of ground or installation lines with
increased potential, which is required to
prevent unintentional contact of service
staff with live parts.
• Separation of control cables from local
control circuits.
• Application also includes test connec-
tions for auxiliary control circuits and / or
local control circuits.
• Grounding of control cables and / or
auxiliary control circuits.
• Bundled disconnection of all auxiliary
control circuits from potential earth.
• A test voltage can be applied using the
screening connection of the control
cable, which is normally routed on the
enclosure, with the help of an appropria-
te separation. This permits to check
whether the screening line is correctly
functioning. For this test, an insulated
feed-through plate is required.

"Terminating Equipment for Pilot Cables
subject to Induced Transient Voltages
exceeding 650 V rms".
