Innovative Solutions
ZTZ Services has continued to innovate where competitors have become stagnant. In 2012, ZTZ originated a new bushing monitor test method which uses both high and low side bushings. This method helps to eliminate uncertainty from varying system voltages or ambient temperatures outside of the optimal range. In 2018, ZTZ was awarded US Patent 10,126,348 B2 for our new method of detecting GIC with our existing bushing sensors, saving the cost of many extra sensors that are required by competing systems.
