Product guide for PrevTech Stray Voltage Control

Key Features

  • Complete On-Farm Diagnostic: Comprehensive stray voltage assessment included with the solution. Identifies external and internal sources, analyzes herd impact, and delivers a detailed report with recommendations.
  • Dynamic Locking System: Approved and certified system that works like a check valve, preventing 60 Hz current feedback from sources external to the livestock building. Provides 24/7 automatic protection.
  • Internal Source Detection: Detects and identifies internal sources of stray voltage including faulty motors, leaking equipment, problematic ventilation systems, faulty electronic lighting, and variable speed drives.
  • Tailored Corrective Measures: Expert recommendations and specialized technical support for each detected source of stray voltage, with accurate diagnosis and guided resolution.
  • Expert Support: Ongoing support from PrevTech electrical safety specialists with deep knowledge of livestock environments and the specific impacts of stray voltage on different species.

Advanced Features

  • Species-Specific Impact Analysis: Diagnostic expertise covers dairy-specific symptoms (nervous cows, high SCC, milking refusal, incomplete milking), hog-specific issues (fewer piglets, reduced weight gain, aggression), and poultry-specific problems (reduced egg production, higher mortality).
  • Turnkey Maintenance Program: Optional annual maintenance program including equipment maintenance, implementation of recommendations, equipment warranty (parts and labor), and free software updates.
  • Post-Installation Validation: Functionality validation tests after installation to confirm stray voltage has been eliminated and the control system is operating correctly.
  • Multi-Source Tracking: Monitors and addresses stray voltage from multiple sources simultaneously: utility company returns, milking equipment, automated ventilation, electronic lighting, and variable speed drives.

Ideal For

Farm Types: Dairy farms (especially those with robotic milking or automated systems), Hog operations, Poultry operations, Any livestock facility with electrical equipment near animals
