Background
This project is located in Ho Chi Minh City, Vietnam, where a machinery manufacturing factory built in the late 20th century urgently needed an upgrade due to aging electrical equipment. The factory required a batch of low-voltage switchgear to improve its power supply capabilities and support the renovation of its low-voltage power distribution system.

ZOLIOV’s Challenge
The local power grid in Vietnam is unstable, and the factory frequently experiences single-phase ground faults. These faults cause voltage imbalances, leading to frequent equipment failures. The factory’s manager, Nguyen Van Nam, reached out to ZOLIOV for assistance.
ZOLIOV’s Solution
ZOLIOV’s technical team worked closely with the customer to fully understand their requirements and developed a tailored solution. After much effort, they resolved the issue by adding a dedicated relay system, effectively preventing equipment failure due to voltage imbalances. ZOLIOV’s solution ensured complete isolation, reducing installation and maintenance work, while ensuring the safety of both personnel and equipment.
