The two phases of polling in Chhattisgarh held on November 12 and November 20 respectively, recorded very fewer glitches and failures from the Ballot units, Control Unit Machines, and Voter Verifiable Paper Audit Trail (VVPAT) as compared to the elections held in the recent past.
During voting, only 0.34% of the ballot units, 0.39% of the control units and 1.89% of the VVPATs had to be replaced. While the results of mock polls stood at 0.72%, 0.88% and 1.68%.
The Election Officers find the figures encouraging as compared with the high rate of failure of EVMs and VVPATs during Lok- Sabha By Polls of Kairana (UP), Palghar and Bhandra-Gondiya
The poll panel used 23,677 control units, 30,696 ballot units and 23,677 VVPATs in the Chhattisgarh assembly polls while it had kept more than 3,900 VVPATs, 2,852 control units and 3,659 ballot units in reserve during the poll-bound state.
In the Karnataka Assembly elections earlier this year on May 12, more than 1,700 VVPATs developed glitches during the mock test, leading to a total of around 4.2% of all the machines.
Following a tremendous amount of Complaints during the Lok Sabha by-elections, the poll panel got its analysis done by the team and experts, which found the excessive amount of exposure to light is the main cause glitches.
The machine’s deplete sensor would malfunction due to the EC logo on printing paper. The thermal paper also absorbed moisture and became heavy and damp, due to which the motor could not move the spool easily. The EC, later got all these issues fixed at the manufacturing level later after the recommendations from the team of experts.
