VIP self-powered protection relay for higher MV
network availability
  • VIP relays are self-powered while traditional
    relays require an auxiliary power supply
  • Self-powered protection relays increase the
    availability of the MV smart grid and are
    perfectly suited to most applications
  • - Insensitive to voltage drop due to faults
  • - Not dependent on UPS systems (weak point of
    electrical installations)
  • Less dependent on the external environment (EMC,
    LV overvoltages) because they require no external
    connections
  • A remote communication making self healing and
    monitoring possible.
  • In addition, the VIP offers optimized
    performances due to integrated protection chain
  • - Complete and pre-tested protection system
    special CT and Mitop actuator savings on space
    and cabling time
  • - High sensitivity sensors

Test operation
  • Primary injection test
  • A primary injection circuit may be permanently
    installed (option) through the CTs, inside the
    cubicle, to test the physical integrity of the
    complete protection system including the CTs
  • - The test is carried out without disconnecting
    the CTs and the VIP relay displays the injected
    current during testing
  • - If necessary, a temporary VIP test mode can be
    activated to test the tripping of the circuit
    breaker by pressing a test pushbutton

Test operation
  • CTs are a block of three dual core CTs, with
    rated insulation voltage 0.72 kV / 3 kV - 1mn,
    providing both measurement and power outputs
  • - The measurement sensor is based on a Low Power
    Current transformer (LPCT) technology according
    to IEC60044-8 standard, which provides an
    excellent accuracy
  • . 5P20 for protection
  • . class 1 for measurement
  • - The power supply winding provides calibrated
    self powering of the relay for few Amps (i.e. 5A
    for VIP40)
  • - Optionally VIP410 can be associated with earth
    fault CT (one single zero sequence CT) dedicated
    to provide a sensitive earth fault protection
    with a low threshold down to 3A
  • - The connection between all these elements is
    prefabricated, protected against external
    aggression, providing a higher level of
    reliability
  • Mitop actuator is a dedicated low power tripping
    coil (Mitop)
  • Specifically designed to operate with the
    sensors and the processing unit with a minimum
    energy
  • Integrity of the Mitop circuit is permanently
    supervised (Trip Circuit Supervision - TCS -
    function).

Typical applications
Self powered protetion chain
35
What is a self powered protection chain?
A self powered protection relay is directly
powered by the current transformers. CT is used
to power the relay and measure detect the
current. The relay does not need any auxiliary
supply
  • A self powered protection chain includes
  • - current transformers (CT) (1),
  • - self powered relay (2),
  • - mitop (3),
  • - and the circuit breaker (4)

Self powered protetion chain
36
What is embedded protection?
It is an optimization of the components (CT
relay tripping coil CB) between them in order
to fulfill the required performance
  • The whole protection chain is integrated and
    pre-tested by Schneider Electric with
  • - Better optimization compared to over
    dimensioned competitors components
  • - Cost effectiveness. Solutions proposed by
    competitors are more expensive
  • - Higher performance. More sensitive to very low
    earth fault current (5A compared to 40A of
    competitors, self powered relays, up to 0,2A for
    VIP dual powered)
  • - Robustness
  • Protection chain is easy to install and
    maintain
  • - No CT selection and calculation. Only two
    sensors for all the new VIP range (200A 600A)
  • - Easy to test protection thanks a specific
    primary injection device. No need to disconnect
    MV cable. No need to have secondary test box.
  • - Avoid wiring testing labour
  • - Shorter delivery time

Self powered protetion chain
37
How is it done today?
Schneider Electric was the first one to propose
an integrated protection chain with VIP30 on RM6
and SFset but with fewer functions. With new
VIP4, Schneider Electric will be the only oneto
propose a fully integrated protection chain
  • Only VIP is a self powered relay, Sepam needs
    an auxiliary power supply.
  • - VIP 30 VIP35 will be substituted by VIP40
    VIP45
  • - VIP300 will be substituted by VIP400

Self powered protetion chain
38
Advantage
  • VIP increases the availability of the MV network
  • - Insensitive to voltage drop due to faults (weak
    point of standard relays)
  • - Not dependent on UPS system (weak point of
    simple electrical installation)
  • - Not dependent on external environment (MEC, LV
    over voltage) because no external connection
  • VIP increases performances due to integrated
    protection chain
  • - Complete and pre-tested protection system
    special CT and Mitop actuator savings on space
    and cabling time
  • - High sensitivity sensors
  • - Cost effective
