"If you see a damaged pole, downed lines or exposed wires you should always treat them as live and the area as a potential electrical hazard, stay well away and contact Unison immediately. Likewise, when digging or driving stakes, you should always have cables located first which is a free service," Park said.
Last month's incidents resulted in 4331 customers experiencing power interruptions which caused considerable disruption.
Unison's ongoing safety campaign continued this month, encouraging residential customers to contact Unison before they begin digging or staking this summer or before they attempted trimming or felling trees near power lines.
The company also offered free electricity programmes for non-electrical contracting businesses working near electricity as well as a free award-winning safety education programme for schools in its network region.
Park said Unison hoped that increasing awareness of these incidents, and the impact they have on both customers and the community, would reduce the number of accidents.
If you come across an accident involving the electricity network, call 111 for emergency services from a safe distance, then contact Unison on 0800 2 UNISON (0800 2 86476) to secure the area.
