Why Power Quality Monitoring Matters:

Power quality issues like harmonics, voltage imbalance and transients silently reduce equipment life and efficiency. By continuously recording and analyzing these parameters, the VT-PM705 helps:

• Identify root causes of motor overheating and transformer stress
• Detect nonlinear loads affecting PF and harmonics
• Enable predictive maintenance through trend and event data
• Improve energy efficiency and system reliability

Applications:

• Industrial plant maintenance and facility audits
• Solar PV power monitoring
• UPS and power supply equipment
• Electrical panel diagnostics
• EV charging infrastructure
• Energy management systems
