OVCD – A comprehensive
protection for you premises

• Overvoltage, and its destructive effects, are
well known but are often not recognized or
understood.
• It often goes undetected because of its
uncertain nature. Its existence is denied due
to this.
Over voltage

3. MSS Powertech Pvt Ltd
• Power companies do not deny its existence;
They do not inform the users of potential
periods in which it may occur.
• Power fluctuations are also caused due to
already connected heavy appliance like a
geyser, grinding machine, refrigerator.
Over voltage

4. MSS Powertech Pvt Ltd
• Power companies cannot prevent overvoltage
because they can only react to its existence,
usually in response to customer (user)
complaints about failing appliances, etc.
• Power companies are mandated by law to
provide service without overvoltage.
IER(Indian Electricity rules) 1959
Over voltage

5. MSS Powertech Pvt Ltd
• Power companies are not held accountable
by any regulation authority for overvoltage.
• Overvoltage can only be proved by the use
of a voltage recorder.
• Over voltage events are misperceived to be
equipment failures leading to their
replacement.

How it works:
• OVCD is connected at incomer of premise before the
distribution box. Incoming current will first pass through
OVCD then into your premises. OVCD continuously
monitors the line voltage.
• Whenever the voltage is above or below the set voltage
limits the OVCD simply cuts off the voltage thereby
saving your premises from the line disturbance.
• OVCD will withstand the voltage even as high as
440Volts in single phase .
• Most equipments get burnt or damaged at this voltage
but not OVCD.

Working: ( contd)
• It however does not stabilize the voltage as in the case
of other devices in the same category like Stabilizer,
CVTs.
• When the voltage returns to normal , the OVCD
resumes the supply automatically with short power-on
delay of 3 seconds(configurable). This feature is called
the Smart Start.
• It prevents the initial harmful transient that may
damage any appliance.
