Power Factor/Tan Delta Test set

M4100 POWER FACTOR / TAN DELTA INSTRUMENT

APPLICATION: High Voltage Apparatus Testing

KEY FEATURES

• Power Factor/Tan Delta testing to confirm insulation integrity and quality
• Capacitance testing to measure physical changes that may have occurred to the apparatus
• Turns ratio testing to detect shorted turns or winding damage
• Leakage reactance/short circuit impedance testing to evaluate winding deformation
• Single phase excitation current testing to evaluate the transformer magnetizing circuit
• Capacitor bank testing to detect deteriorating or failed capacitors within a bank
• Easy and accurate testing with Doble Test Assistant (DTA) software

BENEFITS OF M4100

• Safety is our priority with safety switches, power strobes and ground earth relay interlocks
• Eliminates the effect of varying electrostatic interference with patented Line Frequency Modulation, which makes measurements at a frequency above and below the system frequency
• Reliability & Accuracy – generates its own clean test signal using an internal waveform generator for reliable results and stable readings
• Software firmware system senses abnormal current, temperature and voltage operation even before a user would notice
• Instantly analyze your test results, providing clear recommendations and explanations with FRANK™, the First Response Analytics Knowledgebase

M7100 POWER FACTOR / TAN DELTA INSTRUMENT

The Doble M7100 High-Voltage Asset Analyzer is your complete solution for high-voltage testing.

With an intuitive design and dual high-voltage leads, the M7100 greatly reduces the number of ladder trips technicians are exposed to per job – sometimes cutting the number to nearly one third. This significantly improves the safety and quality of field work by limiting exposure to the workforce and reducing errors.

FEATURES OF M7100

• Built-in Low Voltage/High Current Multi-Frequency Source
• Combined Source and Measurement Test Leads
• True 4-Terminal measurements
• Intuitive design where the color or number is the connection
• Patented dual high-voltage leads allow you to switch between Source and Measurement – both capabilities are within each HV lead
• Enhanced safety features include new safety switch design

BENEFITS OF M7100

• Finish testing in a third of the time
• Maximize your outages and limit safety risk
• Replace a truck full of instruments and cables
• Greatly reduce the number of ladder trips technicians are exposed to per job

DOBLE TEST ASSISTANT (DTA) SOFTWARE FOR M7100

• Collect, analyze and manage test results
• Easy-to-use test plans for two dozen types of HV test apparatus
• Doble QuickHelp pictures for lead connection and test setup guidance
• Manages data by establishing library of every result you collect with DTA
