Installation & Service Manual
Introduction
The reliability of electrical power to industry is in general very high, nevertheless,
voltage sags or dips do occur. These instabilities are caused by short circuits, lightning
strikes on overhead power lines and heavy load switching. The duration of such faults is
generally shorter than one second. Power Quality data shows that voltage sags with a
maximum depth of around 50% constitute 92% of all events.
Most plant can ride through such voltage dips by virtue of their mechanical
and electrical inertia. However, this is not the case with electrically held-in contactors and
relays that control the machinery. Contactors typically drop out from 5ms to 20ms after
power is removed. Each short voltage dip now becomes a power failure and the plant must
be restarted. This can be complicated, time-consuming and costly.
DIP-PROOFING TECHNOLOGIES’ Voltage Dip Compensators are designed to maintain the switchgear control voltage during voltage sags, effectively keeping
the plant connected. The stored electrical and magnetic energy is allowed to flow,
supporting the mechanical inertia of the machinery. When the power is restored after a
short voltage dip, the plant is still running at near synchronous speed, the inrush currents
will be small and the stress to the system minimal. The VDC provides an economic
solution for users who need their equipment to comply with the Semi F47 standard for
voltage sag immunity.
Historically, this problem has been addressed by using DC contactors,
latched contactors and intelligent controls such as PLC’s. These systems are complex
and expensive and do not provide a solution for equipment already in existence. The
current approach to this problem has been to employ intelligent control systems which
provide a curative solution. In contrast, the Voltage Dip Compensator, provides a
preventative solution.
Theory of operation
The VOLTAGE-DIP COMPENSATOR is designed to be maintenance free and
highly reliable. It consists of 5/7 static switches , a sag compensation transformer and the
controls. The Voltage Dip Compensator block diagram is shown in Fig 1 below.

The STATIC SWITCHES are robust and can withstand large current surges. They
are ideally suited for contactor operation where high peak currents of short duration occur
during energizing.

Compensator output waveform.
During stand-by operation, static switch1 supplies power directly to the load,static
switches 2 to 5 are switched off and the compensation transformer carries no load. The
supply voltage is constantly monitored for deviations; should there be a deviation from
Vnom which is greater than ±10%, static switch 1 is switched off and static switch 2 is
activated. Depending on the sag depth the controls will operate static switches 2 to 5/7
to maintain the compensator output voltage within ±10% of the nominal supply voltage.The
switch-over is accomplished in 350µs. A 3.15 second timer, adjustable in increments of
50ms , starts timing the compensator out. Should the input voltage recover within the set
time, static switches 2 to 5/7 will be deactivated and static switch 1 will be switched on and
the load is reconnected to the supply. If the input voltage does not recover within the set
time the load is switched back to the supply regardless of the voltage level. If I2t control
is enabled then the run time will be dynamically optimized to the longest time that load
conditions will allow.
The VDC employs tap switch fuses to prevent catastrophic damage to the unit in
the event of a tap switch failure. If a tap switch should fail the fuse will open. A VDC with
a failed tap switch will continue to function normally and will attempt to serve any sags that
occur. However if sag conditions require activation of the failed tap then the load will be
dropped because there is no output from that tap.

Installation & Service Manual
Installation Guide
1.
Remove the unit from its packing
2.
Place the unit horizontally on a bench and visually check for any
mechanical damage. Ensure that all the casing screws are tight then
shake the unit to check that there is nothing loose internally.
Note : Please inform your shipping agent if any damage has occurred
during transit : the damaged unit(s) and all packing material should be
kept in case the insurers wish to inspect the damage.
3.
Check that compensator voltage is the same as the system control voltage.
Refer to the rating label on the unit end plate.
WARNING: Never connect a 120V unit to a 208V or 230V supply!
4.
Decide on the location where the unit is to be installed, this will probably
be inside a switch gear panel.
5.
Mount the unit vertically using M6 bolts.
6.
Connect unit as shown in Fig 7 using 2mm2 (14AWG), VDC S series & 5mm2
(10AWG), VDC L series copper panel wire.
7.
Apply terminal screw tightening torque of 0.6 - 0.8Nm (5.2 - 7 lb-in), VDC S series
& 1.5 - 1.8Nm (13 - 16 lb-in) VDC L series.
8.
This device does not have a disconnect switch. If such a switch is required it
must be provided by others.

Once the unit has been mounted and the external wiring completed, power
can be applied.Turn on the power to the unit. The green LED indicator
"System OK" will come on after approximately one second and the unit is
fully operational.

In applications which require no break maintenance, a bypass switch
must be installed. Order the appropriate Bypass Switch (see p17) which
should be connected as shown in Fig 8.

Compensator Run Time
Timer controlled Run Time - SW1 (see Fig.11 page 13)
This switch sets the running time of the compensator and can be set in 50ms steps to a
maximum of 3.15 seconds. To determine the run time which is currently set, add the
figures printed next to each switch that is in the ON position. For example, a running time
setting of 3.15 seconds requires these switch combinations: 1-on, 2-on, 3-on, 4-on, 5-on,
6-on.
I2t controlled Run Time.
Run Time is dynamically optimized to the longest that load conditions will allow.
The I2t optimized Run Time can be determined using the curves on page 12.
To enable this option set all SW1 switches to OFF.

that make up the case are interlocked and secured by screws. To remove the front cover
unscrew four screws : the two top screws from the end plate where the terminal block is
located and the two bottom screws from the other end plate. Slide the front cover away
from the terminal block to access adjustment area.
VDC L series - The VDC case is made from extruded aluminium sections. The six parts
that make up the case are interlocked and secured by screws. To remove the front cover
unscrew three screws : one from the front cover and one each from the top and bottom
end plates.

Housed Bypass Switch
Description
Where no-break maintenance is required a by pass switch must be installed. It connects
the supply directly to the load, "Bypass" position, and disconnects the power terminals of
the inverter without interrupting the supply. When in "DPI" position the load is connected
to the supply via the inverter.

VDC L4T/L6T & VDC S4T/S6T Series - Firmware ver 1.4 & up
Installation & Service Manual
The Sag Simulator is an effective tool to
evaluate the effects of momentary voltage sags
and interruptions on industrial controls. When
used in conjunction with a Voltage Dip-Proofing Inverter or a Voltage Dip Compensator and
Bypass switch, it may be used to prove the
effectiveness of the DPI or VDC as a solution
for these power quality problems.
The Sag Simulator is designed for 120/208/
240Vac operation. The controls consist of a
variac to set the sag depth, an LCD display to
indicate the sag voltage value and program
status, four programming keys to set up and
operate the simulator. A variable interrupt timer
sets the duration of the voltage sag and the
point in the cycle at which it begins. Both
variables are set using the programming keys
and are indicated on the LCD display.
Simulator output is short circuit and overload
protected. A 5V synchronization pulse is provided to trigger an oscilloscope. A photograph
appears on page 8; the specifications are shown
below.
