ProTec T1S 

Phase GDT Technology

Features & Benefits

The features and benefits of this new 
PGDT technology may be summarizes 
as follows:

 

•

Compliant with IEC Class I testing 
per IEC 61643-11 - making it suitable 
for use in locations where direct, or 
partial direct, lightning currents can 
be expected per IEC 62305-4.

 

•

VDE mark - certified to applicable 
IEC and European norms under low 
voltage directives.

 

•

High surge capacity but without the 
problems of follow-current extin- 
guishing - can be installed on 
networks having high prospective 
short circuit fault currents (SCCR).

 

•

Tested to be suitable for repeated 
operations on networks with Ip as 
high as 50 kA 50/60 Hz.

 

•

Multi-cell design reduces follow- 
current to the point it behaves much 
like MOV based technology - unlike 
conventional spark gap technology 
where the high follow-current causes 
the gap electrodes to degrade after 
each operation, PGDT provides a 
long operational life. 

 

•

Low residual voltage U

p

 = 1.5 kV – 

can effectively be coordinated with 
other Class II or Class III SPDs on 
the network. It can be coordinated 
with any properly installed Class II 
SPD without the need to consider 
cable length in between the products.

 

•

High surge rating in a compact, 
pluggable, DIN package – half the 
footprint of competitive products 
optimizes panel board real estate.

 

•

Encapsulated design, vital parts are 
housed inside a hermetically sealed 
cell – no expulsion of hot, conductive, 
ionized gasses.

 

•

Change over contacts for remote 
monitoring

 

•

Efficient internal mechanical thermal 
disconnects – enables safe and relia-
ble end-of-life behaviour on networks

 

•

Red/Green status indicator

The ProTec T1S Series is the latest evolution in 
surge protection from Raycap. At 25 kA (10/350 μs) 
in a 1TE (17.5 mm) DIN package, it is the most 
compact pluggable surge protective device on the 
market.
ProTec T1S utilizes a breakthrough multi-cell, 
encapsulated GDT technology, to achieve a 
residual voltage like that of an MOV-based SPD, but 
in a footprint half the size of the market competition 
and without restrictions governing where on a 
network it may be installed.
Raycap has a long tradition of utilizing materials in a 
way to provide robustness and long-lived products. 
Combining this knowledge with a new patented 
multi-cell GDT technology offers customers a 
solution that can be used in heavy lightning 
intensive environments.

Lorem ipsum

The follow-current of PGDT technology is 

compared to that of conventional air-spark 

gap technology. Conventional air gaps need to 

migrate the arc away from the main electrodes 

to lengthen, and ultimately extinguish it. This 

process of moving the arc takes a finite time 

during which the follow-current increases. 

PGDT technology uses the multi-cell approach 

to circumvent this limitation and lower the 

follow-current.

SafeTec delivers a reliable solution for all 
overvoltages, surges and transients. The 
all in one technology is suitable for all DC 
and AC applications. The patented SafeTec 
technology is an open circuit mode in 
combination with current limiting technology. 
This current limiting control prevents 
permanent disconnection during adverse 
temporary overvoltage (TOV) conditions.

Driven by the need for higher reliability, 
system cost reductions and market needs, 
SafeTec technology addresses significant 

performance improvements in a new 
industrial design. The patented SafeTec 
technology serves as a current limiter in the 
event of unexpected faults in power supply 
networks and ensures that the maximum 
current through the MOV in the initial 
state of conductivity is a few ampere. The 
current balance is quickly established at a 
level of about 10 mA. The unique SafeTec 
technology ensures that the current does 
not exceed the MOVs energy handling 
capability, and prevents unwanted SPD 
disconnection from the power supply.

ProGRID Surge Counters & Monitors

Surge currents can cause loss of data 
transmission, switch tripping, disturbance 
of machine control systems and a slow but 
noticeable degradation of circuit elements. 
In addition, a surge can be an indicator of a 
short circuit which causes currents of power 
to travel along unintended paths with little or 
no electrical impedance, for example after a 
blackout or wiring insulation damage. 
Raycap’s ProGRID surge and lightning 
counter solutions have different capabilities 
that can sense, record and transmit the 
occurrence of otherwise undetectable 
surge currents, enabling users to take 
preventive measures and plan appropriate 
maintenance.

eMobility - Charging Protection

Raycap provides standard and customized 
AC and DC SPD solutions for electrical 
vehicle (EV) charging technologies, such 
as AC direct charging, DC low voltage 
charging and next generation DC high 
voltage charging (fast charging). A unique 
challenge of DC high voltage charging is 
the reduction of overvoltage coming into the 
electrical vehicles and damaging circuitry. 
With this in mind, Raycap has designed and 
manufactured DC SPD solutions dedicated 
to mitigating the risk of this happening.

eMobility solutions present opportunities for cleaner vehicle emissions. The convenience of having charging 
stations in many areas helps to enable the technology. Another important factor is the electrical protection of these 
locations, and the cars themselves.

to the wind farm operator. Wind turbine 
manufacturers integrate Raycap’s surge 
protection and monitoring products into 
various locations of the wind turbine. From 
the wind turbine generator to the sensitive 
communications and monitoring equipment 
located inside, all systems must be 
protected from and monitored for powerful 
lightning surges.

Wind turbines are especially susceptible to damage from lightning strikes. When 
compared to costly repairs and unnecessary downtime caused by lightning strikes, the 
relatively low cost of Raycap solutions far outweighs the alternative.

Water & Wastewater 
Treatment Facilities

Water and wastewater treatment systems 
are heavily dependent upon a series of 
pumps and variable frequency drives 
(VFDs) which can be extremely susceptible 
to damage from electrical surges.
In these applications surge protection is 
integrated directly into the equipment by the 
original equipment manufacturer to protect 
the VFDs.

Power Distribution Networks

Power distribution grids are particularly 
susceptible to lightning surges, causing system 
outages and affecting the reliability of the 
power supply, resulting in enormous financial 
burden. The transfer of overvoltages to the 
low voltage side is mainly associated with a 
rise in potential at the transformer grounding 
caused by current flowing through the medium 
voltage surge arresters and creating an 
electromagnetic coupling between the medium-
voltage and low-voltage transformer terminals. 
Installing surge protection significantly 
reduces the overvoltages to safe lower peak 
values which remain practically unaffected by 
transformer and/or load grounding resistances.  

Raycap’s electrical protection solutions can safeguard power distribution equipment and help prevent transformer 
failures, saving money and protecting the backbone of the power grid.

Mining &  
Oil & Gas Applications

When mining facilities have to interrupt their 
operations, downtime can be very expensive 
and repair costs can be high. Therefore, surge 
protection devices play an important role in 
these installations, because uninterrupted and 
maintenance-free operation above and below 
ground must be guaranteed. 
Pumping stations and transport systems for 
crude and shale oil and natural gas must be 
protected against dangerous surge conditions 
and lightning discharges.
In these applications, Rayvoss SPDs, 
Strikesorb assemblies and other SPD solutions 
are used to protect and monitor various 
electrical systems inside and outside the 
production facilities.

Raycap’s surge protection solutions are deployed at oil and gas pumping, processing, and transfer stations to 
safeguard vulnerable equipment and protect the entire operation from damage caused by lightning strikes.
