STATIC VOLTAGE
REGULATOR
Static Voltage Regulator is a Thyristorcontrolled microprocessor-based electronic
device, having an Isolation Transformer &
RFI/EMI filters. It regulates fluctuating
voltages in a precise manner & constitutes a
high-level spike suppression system which
protects the equipment by virtually
eliminating any transients in the distribution
network.
Static Voltage Regulator is most suitable for
24-hour continuous process operations
where break downs due to fluctuations
results in heavy financial losses and damage
of expensive equipments.
APPLICATIONS
TECHNOLOGY
SVR regulates the voltage through the tapping selection
by means of semi-conductor static switching devices viz.
Thyristors, IGBTs which respond instantaneously. In
addition, microprocessor-based control circuitry along
with Thyristors results in high correction speed and higher
efficiency. There is no moving part inside SVR and it is a
fully electronic & automatic unit.

COMPARISON BETWEEN STATIC VOLTAGE REGULATOR & SERVO VOLTAGE STABILIZER
Static Voltage Regulator
Servo Voltage Stabilizer
Output voltage is regulated by using multi-tapping
transformer or Buck Boost transformer
Output voltage is regulated by using double wound dimmer
Wider Input voltage range:
155 VAC - 502 VAC
Input voltage range: 260 VAC - 450 VAC
Switching devices are Semiconductors like Thyristors
and Triacs which improves the reliability of the system.
Switching device is Relay which is a electro-mechanical device
& is less reliable as compared to semiconductor devices.
No moving part inside and is a fully electronic unit.
Carbon brushes generate sparks and Gear assembly makes
noises. It is prone to frequent wear and tear that requires
regular maintenance.
Correction speed is very fast, almost 1000 V/Sec.
Rate of correction is slow, almost 30 V/Sec.
Response time is higher
Poor Response time
No cooling oil required
Oil cooling is messy & is required to be changed periodically
