Bowthorpe EMP is a manufacturer of surge protectors for Mains Power, Voice and Data Systems and High Voltage surge arresters.
An extensive range of products is available to meet demanding applications and diverse power and communications systems environments worldwide.
Tyco Electronics Energy Division
covers a wide range of porcelain and
polymeric transmission surge
arresters. The Bowthorpe EMP range
of arresters has demonstrated
reliable performance in
environments all over the world for
over 60 years.
Bowthorpe EMP, unlike other
manufacturers, recognise that some
Power Utilities require the need to
maintain the conventional ZnO
porcelain surge arrester.
A program of continuous design
update and development on the
porcelain arrester has provided a
range of surge arresters to meet the
demands of most system voltages.
Design Evaluated and Type Tested at
the HV Laboratory in Brighton.
Bowthorpe EMP were the first
manufacturer to develop the
polymeric housed arrester for
commercial operation (1983).
Range of HV surge arresters in
service under the severest climatic
conditions up to 550kV system.
The range of arresters are unique,
covered by worldwide patents to
protect the company's extensive
investment in R & D.
The Bowthorpe EMP range of Surge
Arrester monitoring instruments are
fully tested for use with any
manufacturers surge arrester.The
SC12 is a Surge Counter only, whilst
the SC13 provides the additional
measurement of total leakage
current. The analogue instrument
provides a means of monitoring the
current through the arrester and the
leakage current over the surface of
the arrester housing. Significant
changes after installation may
indicate a deterioration in the
arrester or a build up of surface
These instruments, which require no
auxiliary supply, are designed for
installation in the earth connections
of a single surge arrester or
alternatively the SC12 may be used
with the common earth of a three
phase set. Fully weatherproofed and
sealed for life they are housed in a
one piece gravity die cast aluminium
case coated to enhance its already
high degree of resistance to surface
corrosion. The glass viewing window
is sealed in place, using a silicon
rubber adhesive, and a desiccator is
enclosed to ensure any residual
moisture trapped during sealing is
absorbed for the service life of the
counter. Mounting is effected by
means of an integrally cast lug at the
rear of the case
providing a single clearance hole for
the galvanised steel M12 bolt
The SC12 and SC13 are service
proven and require no special
maintenance or servicing apart from
general cleaning of the glass
viewing window and the moulded
epoxy resin line terminal bushing.
