Raycap Core Values

Din Rail Solutions for
Low Voltage Power & Signal Protection
Appendix 1

Common sources of SPD failures
TOV – Sustained overvoltages of the network (50/60 Hz) with
significant duration and amplitude. Causes include switching
resonance, system faults, loss of neutral conductor etc…)
Dissipative effects – Repetitive surges of short duration,
resulting in long-term degradation of the SPD
Destructive effects – Surges exceeding the max rating of the
SPD, resulting in immediate equipment failure

SafeTec Technology
Reliable DIN rail technology in situations where TOVs or
switching transients may be present on the distribution
network
 TOV immunity - Patented current limiting circuit
 5 year warranty (10 year lifespan)
 Good protection level
 Low maintenance cost

OCM
Open Circuit
Mode
2S OCM
2 States Open
Circuit Mode
Open Circuit Mode (OCM) - disconnection from power supply network using
internal thermal disconnector or external series fuse
2 States Open Circuit Mode (2S OCM) – disconnection from power supply
network using internal thermal disconnector and internal parallel fuse
Common approaches to DIN Rail SPD disconnection
Issues
 Danger of arcing
 Permanent disconnection
during TOVs – requires
replacement of product
 Higher maintenance costs
 The time lag for the thermal
disconnector to operate may be too
long to operate safely - Risk of
catastrophic failure

SafeTec
current limiting technology
SafeTec technology is Open Circuit Mode in
combination with Current Limiting Technology
Open Circuit Mode (OCM) - disconnection from
power supply network using internal or external fuse
in combination with different components.
2 States Mode (2SM) - a combination of Open Circuit
Mode (OCM) and Short Circuit Mode (SCM).
Short Circuit Mode (SCM) - conducts available
current directly to the ground by short circuiting
internal components.

SafeTec Technology
Raycap's SafeTec surge protective technology
provides protection from damage caused by
electrical surges. It mitigates the risk of damage
due to overvoltages and provides high levels of
availability and reliability to the protected
equipment.
 Category UL 1449 4th Ed.: Type 2
 Location of use: Sub-distribution boards
 Protection Modes: L-G (PE), L-N, N-G (PE), or L-L
 Protective element: MOV and GDT

With SafeTec
technology,
the TOV

safely limited,
preventing
damage to the
MOV.

Two possible types of overvoltages may appear in the power supply
network, and SafeTec technology is a great solution for both.

Transient overvoltages
(switching operations, atmospheric
discharges, etc.) can last for a short
period of time.
Temporary overvoltages
(TOVs) can last for a longer period of
time. Voltage amplitude can reach
173% UREF.

Technology Activation in the case of TOV
1. In the event of a network failure the current starts flowing and reaches the peak value
2. The current is limited with SafeTec technology
3. The ohmic value of the current limiter escalates, the current value decreases
4. The current value is decreasing until the current value stabilizes to a few mA

ProLEC Wind Solution:
Remote sensors and base station
Appendix 4

ProLEC Wind Solution
ProLEC Wind is a system which provides wind
farm operators with the ability to accurately
identify when lightning strikes the blade of wind
turbine.
The system consists of Remote Sensors which
are installed in the turbines blades and a Base
Station.
The sensors communicate with the base station
through latest IoT (Internet of Things) wireless
technology, and the base station sends data
through RF or Fiber to operators private server.

Sensor & Base Station Installation
One Remote Sensor is installed at each blade
 Very simple to install
 Sensor secured inside blade
 Existing blade is unaffected
 Wireless solution
 Sensor is powered by a battery with 2 year life
Wireless Base Station
 Has a range of 10km and is able to
communicate with any number of remote
sensors within this range
 The base station requires power. Typically
these are powered by a 240V source in one of
the turbines
Sensor
Base Station

Benefits of ProLEC Wind
ProLEC Wind immediately
identifies when a blade is struck by
lightning.
The wind farm operator is alerted to
which turbine been struck and
where.
ProLEC is wireless and existing
turbines can easily be retrofitted
with ProLEC sensors.
ProLEC sensors can send
information on a daily, weekly,
monthly basis

Temporary overvoltage (TOV) versus SPDs
• Temporary overvoltage (TOV) describes an long term overvoltage above nominal voltage
(Un) incl. tolerance (typically e.g. 20%) for a limited time (msec to sec). The voltage level
can reach the double of Un.
• TOV occurs during earth faults, load rejection or phase opposition during synchronization
of two grids. It is also a typical phenomena of ‘weak’ grid systems with long cable
distances between MV/LV transformer and load (e.g. a remote telecom station).
• SPDs are designed to response very fast and to limit high voltage Spikes (protection level
is typically 3…3.5 times Unpk)
• SPDs should not response to TOV -- if protection level of SPDs is rated too low there is a
risk SPDs getting damaged during TOV conditions (overload) or backup fuses will trigger.

Passive Energy Absorber
• Passive Energy Absorbers are designed to limit a TOVs to approx. 1.8 times the nominal peak
voltage.
• They are MOV based and can handle significant higher energy compared to classical SPDs.
Main application is protection of semiconductor and generator windings during load rejections
with generated voltages up to 3*Unpk.
• They are not optimized for handling surges and transients and are not conform IEC SPD
standards.

• Active Energy Absorbers are designed to limit a TOV to approx. 1.2 times the nominal peak voltage.
• They are MOV based in combination with a switching element (semiconductor) and can handle
significant higher energy compared to classical SPDs.
• Main application is protection of TOV sensitive electronic devices when the clamping voltage has to
be very low in comparison with the normal operating voltage.
• They are not optimized for handling surges and transients and are not conform IEC SPD standards.
