The Megger S1-Series of insulation resistance testers consist of 5 kV, 10 kV, and 15 kV models called S1-568, S1-1068 and S1-1568. These 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, 5kV and10 kV models are safety-rated to CAT IV 600V at altitudes up to 3000m and the 15kV S1-1568 is rated at CAT IV 1000V at altitude up to 4000m. 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 has 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 Polarization 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 onboard Bluetooth interface is used for the 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 3kV equivalent to 6kV single insulation for the medium clip lead set and 5kV equivalent to 10kV single insulation for the large clip. The 15kV lead set is insulated to 15kV.
