S1-568 and S1-1068
5 & 10 kV DC Insulation Resistance Testers
DESCRIPTION
Megger’s new S1-Series of insulation resistance testers consist
of a 5 kV model, S1-568 and a 10 kV model, S1-1068.
These top end instruments are targeted at power utilities
and service companies working in generation, transmission
and distribution markets. Class leading charge current, noise
rejection and software filters make the S1-Series Megger’s
most advanced DC insulation resistance testers to date.
Instrument productivity is a focus of the new S1-Series which
offers rapid charge batteries and operation from an AC source
when the battery is flat. An intuitive user interface ensures
no lost time remembering how to use the tester. Simplicity
of operation is achieved with two rotary switches and a large
backlight display which enables multiple results to be displayed
simultaneously. A graphical quick start guide is provided inside
the lid of each model to assist first time users.
Safety of operation is built in, 5 kV and 10 kV models
are safety rated to CAT IV 600 V up to 3000 m. Original
equipment manufacturers and repairers will welcome the
remote control feature allowing them to automate resistance
testing on the factory floor, as will technicians in substations
wanting to operate from a more convenient, safe distance.
The S1-Series have a dual case design with a tough outer
case to protect the tester from knocks and drops and a fire
retardant inner case. The case IP rating prevents moisture and
dust ingress when storing or carrying the instrument. The lids
have clip-on lead pouches ensuring that leads remain with the
instrument at all times. Case lids are removable for improved
access to the terminals.
Five preset voltage ranges are provided in insulation test
mode, plus a user settable lock voltage range. Preconfigured
diagnostic tests include Polarisation Index (PI), Dielectric
Absorption Ratio (DAR), Dielectric Discharge (DD), Stepped
Voltage (SV) and Ramp test.
Advanced memory storage includes time/date stamping of
results, logging of data and recall of results to screen. A fully
isolated USB interface or on-board Bluetooth® interface is
used for safe transfer of data to Megger’s asset management
software; PowerDB Pro, Advanced or Lite packages.
Test leads are double insulated with clamps rated at 3 kV t
equivalent to 6 kV single insulation for the medium clip leadset
and 5 kV t equivalent to 10 kV single insulation for the large
clip leadset.
