Megger S1-1068 10 kV DC Insulation Resistance Tester

Megger S1-1068 Insulation Resistance Tester
Megger’s new S1-Series of insulation resistance testers consist of a 5 kV, 10 kV and 15 kV models called S1-568, S1-1068 and S1-1568. 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  and  the  15  kV  S1-1568  is  rated  at  CAT IV 1000 V up to 4000 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.

he  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  tequivalent to 6 kV single insulation for the medium clip leadset and  5 kV t equivalent to 10 kV single insulation for the large clip. The 15 kV leadset is insulated to 15 kV.

APPLICATION
The Insulation Resistance (IR) test is a quantitative test which indicates the  effectiveness  of  a  product’s  electrical  insulation.  Applications  include cables, transformers, motors/generators, circuit breakers and bushings. Common insulation tests are the “spot test”, a 1 minute IR test and a 10 minute Polarisation Index (PI) test, where PI is the ratio R10min / R1min and is temperature independent.
