General The following instructions are for eld and shop programming of the S&C Overcurrent
Control. This microprocessor-based control is designed for use on S&C Vista Under-
ground Distribution Switchgear to provide fault detection and operation of the resettable,
vacuum fault interrupters. Each overcurrent control operates up to six single-pole fault
interrupters or two three-pole fault interrupters. The control is housed in an enclosure
which is mounted on the operation side of the switchgear. For UnderCover and Wet-Vault-
Mounted Style Vista units, the enclosure is fully submersible. The electronics module is
removable for programming in the shop.
Programming A personal computer furnished by the user is to be used to input settings, review set-
tings, and interrogate the event recorder. The software for programming the overcurrent
control is contained within the control. Two data ports are provided—one on the
enclosure for programming in the eld, and another on the electronics module for
programming in the shop. Adapter cables are available from S&C (see Instruction Sheet
681-515A) to connect the computer to the control.
An external power source is required for programming and interrogating the control.
A source of dc power is available from the mouse or USB port on the personal computer.
The adapter cables contain connectors for data and power to utilize the power available
from the computer.
Description
S&C Instruction Sheet 681-515 5

Power and Sensing Current transformers are provided inside the switchgear tank for each set of three single-
pole fault interrupters or each three-pole fault interrupter. These current transformers
provide primary current sensing ranging from 50 to 12,500 amperes (100 to 25,000 amperes
for 900-ampere and 1200-ampere models). Vista UDS rated above 12.5 kA short circuit
will respond to fault currents above 12.5 kA, but the event log will only record that a fault
above 12.5 kA has occurred (or 25 kA for 900-ampere and 1200-ampere models). The
overcurrent control is capable of sensing and responding to both phase overcurrents and
ground overcurrents.
The power derived from the current transformers is used to operate the control and
to charge the trip capacitors which discharge into magnetic latching solenoids to trip the
fault interrupters during a fault. No external power is required for operation of the control
in the field.
Time-Current
Characteristics
The overcurrent control features time-current characteristic (TCC) curves consisting
of phase-overcurrent curves and ground-overcurrent curves. The families of curves are
included as follows:
• S&C Standard Speed curves (for use in place of conventional “E” rated power fuses.
• S&C “K” Speed curves (for use in place of conventional “K” rated power fuses).
• Tap Fault Interrupter curves.
• Main Fault Interrupter curves.
• ANSI U.S. and IEC curves per IEEE Standard C37.112-1996 U1, U2, U3, U4, U5, C1, C2,
C3, C4, and C5.
The tap and main fault-interrupter TCC curves can be customized into hundreds
of different curves using a variety of instantaneous-pickup settings (discrete choices
from 0.2 kA through 6 kA), and definite-time delay settings (discrete choices from
32 ms through 128 ms). For even more specialized shapes, an instantaneous-pickup
setting can be combined with a definite-time delay setting. The minimum total
clearing time—from initiation of the fault to total clearing—is 40 milliseconds.▲
Settings
(See Appendix E for a
complete list of settings)
The overcurrent control has a phase-overcurrent pickup setting and an independent
ground-overcurrent pickup setting for each set of three single-pole fault interrupters or
each three-pole fault interrupter.
The input parameters for both the phase- and ground-overcurrent curves include
minimum pickup levels, instantaneous-pickup levels, and definite-time delays.
Phase-overcurrent pickup settings and ground-overcurrent pickup settings are made
independently. If desired, the ground-overcurrent curve and the instantaneous-
pickup and definite-time-delay attributes can be disabled. When E-speed or K-speed
curves are selected, the ground-overcurrent pickup setting is disabled as are the
instantaneous-pickup and definite-time-delay attributes. An example of how to select set-
tings for the overcurrent control is shown in Appendix D.
A choice of 50- or 60-hertz operation are also offered. For single-pole fault interrupters,
a choice of single-pole or three-pole trip is also offered (single-pole tripping is not possible
with three-pole fault interrupters).
▲The definite-time delay setting will override the instantaneous setting when the definite-time delay setting is activated before the instantaneous
setting.
Description
6 S&C Instruction Sheet 681-515

Event Recording The overcurrent control features an internal event recorder that captures the last
twelve fault operations for each fault interrupter. The event log indicates which poles
have experienced a fault, the magnitude of the fault, and whether or not a ground
overcurrent was involved. This information can be accessed via a personal computer
connected to the data port of the control.
Self Testing Whenever the overcurrent control is powered up—and then periodically thereaf-
ter—it automatically goes through a self-test procedure to test vital subsystems and
ensure proper operation. The control checks the trip capacitors, power-supply volt-
age, RAM, EEPROM, integrity of the data, and voltage control. It then ags whatever
fails the self-test.
Single-Pole or
Three-Pole Tripping
Three-pole fault interrupters are factory-programmed for three-pole tripping. This
setting should not be changed since single-pole tripping is not possible with three-
pole fault interrupters. However, when used with single-pole fault interrupters, the
overcurrent control can be programmed for either single-pole or three-pole tripping
of the fault interrupters. Single-pole tripping operation is when the control trips
only those fault interrupters on the phases that have experienced a fault. When set
for single-pole tripping operation, the control will not trip the fault interrupters in
response to a ground fault, but will respond to a phase overcurrent—whether or not
it involves ground.
Three-pole tripping operation is when the control trips all three fault interrupters
regardless of which phase has experienced a fault. For three-pole tripping operation,
a ground-fault setting is available and the control will operate the fault interrupters
in response to a ground overcurrent.
Description
S&C Instruction Sheet 681-515 7

Connecting a Personal Computer
A data port for communications is provided at the top of
the enclosure that houses the overcurrent control. This
data port, which is connected to the electronics module
inside the enclosure, cannot draw power from the control
and must be powered from an external source while in
use. When the data port is in use, the power-connection
points (Pins 1 and 4) power the control. The allowable
voltage range is 4 – 5 Vdc, and the power consumption is
1.8 W nominal, 2.2 W maximum.
Adapter cables are available from S&C (see Instruction
Sheet 681-515A) for connecting the control to a user-furnished
personal computer in the field. These cables provide for both
communications and power.
For Microsoft Windows users, no special software is
required to communicate with the control. The user interface
is menu driven within the control. Use the HyperTerminal
program provided with Microsoft Windows or other terminal
emulator program to set or interrogate the control.
Microsoft Windows Vista™, Windows®7, and Windows®8
users will have to install a terminal emulator program. See
Appendix C for further instructions.
Setting the Communication Parameters

Electronics and
Burden Board DANGER
Never disconnect CT secondary circuits without de-energizing the switchgear. Hazardous
voltage will shock, burn, or cause death.
CAUTION
When the electronics module is removed from its enclosure, the associated fault interrupt-
ers will not provide fault protection
The overcurrent control consists of an electronics module and a burden-board module
(burden board and base plate). Two current transformers (CTs) are provided for each
fault-interrupter pole; one supplies measurement current for the control and the other
supplies power for the control. The burden board recties the power and also transforms
the measurement current from the CT secondaries into voltage. It then passes rectied
power and current signals to the electronics module. The burden board provides the
burden for the CTs so that the electronics module can be removed and replaced while
the Vista switchgear is energized. A grounded shield protects the user from contact with
the CT secondaries should the secondaries become disconnected from the burden board.
Removing the
Electronics Module
1. Loosen the captive screws or bolts
that secure the cover of the control’s
enclosure in place and remove the
cover.
Four captive screws
secure cover to Pad-Mounted or
Dry-Vault-Mounted Style enclosures;

CAUTION
ALWAYS disconnect the trip connectors from the electronics module before removing the
module from the base plate. Failure to follow this precaution may result in the unex-
pected operation of a fault interrupter.
Trip connectors—loosen both trip connectors and remove
them from electronics module

4. Grasp the electronics module by the handle and lift it upward slightly away from
the base plate. This raises the stand-off attached to the inside of the cover of the
electronics module, allowing the CT shorting clip to make its connection to the
power CT secondaries and short circuit the secondaries. After the CT secondar-
ies are short circuited, the connection between the electronics module and the
burden-board module breaks.

The View Event Report option allows viewing of the last 12 recorded events for the
selected fault interrupter. The report includes faulted poles and whether ground was
involved, primary RMS current magnitude and ground current for each pole, at the exact
instant that fault current is detected (which values may not always make sense), and the
time since the last event. The time is not displayed if there has been no other event since
power up or if more than 60 seconds has elapsed since the previous report.
New events are inserted at the number 1 position. When the list is full, the oldest event
will drop from the list. Faulted poles are indicated by an “X.”
The overcurrent control stores a nonvolatile short event report each time it issues a
trip pulse. The short event report contains the following information:
• The faulted pole(s) and whether ground was involved. The “target” (X) logic is as
follows:
1. Target any faulted poles that caused a trip.
2. Target any phase faulted pole with current greater than the phase time overcurrent
