M4100
High Voltage Apparatus Tester
The industry standard for commissioning, diagnostic, and preventative testing
The M4100’s unique combination of test capabilities and artificial intelligence analysis software makes it the power industry’s most trusted Power Factor/Tan-Delta instrument.
The M4100 instruments are used around the globe thanks to their comprehensive testing options, safety features and measurement accuracy.
Testing is simple and accurate with the M4100 and Doble Test Assistant (DTA) software. You can then analyze your test results with the help of FRANK™, the First Response Analytics Knowledgebase, which provides clear recommendations and explanations.
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
- 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
ACCESSORIES
M4110 Leakage Reactance Interface
The M4110 Leakage Reactance Interface (Figure 1-7) provides a power source and signal conditioning that allows the M4100 to measure transformer leakage reactance, also known as short-circuit impedance. The Leakage Reactance test cannot be run without this interface. Current and voltage cables are provided for connection to the transformer. The safety switch and safety strobe are required for this interface.M4151 Field Calibration Reference
The M4151 Field Calibration Reference module enables the M4100 to perform System Status, Calibration Verification, and Field Recalibration tests in the field. When included, the M4151 is integrated into to the body of the M4100.The M4150 Field Calibration Reference, with two sets of terminals instead of three, is no longer available.Type C Resonating Inductor
The Type C Resonating Inductor is an adjustable reactor that extends the charging current range of the M4100 to test larger apparatus.M4300 Transport
In one configuration, the M4300 Transport moves and stores the M4100 system.dobleTTR Capacitor
The TTR (Transformer-Turns-Ratio) Testing Capacitor is a small, portable capacitor that can be energized at up to 10 kV for performing turns-ratio tests with the M4100 at high voltages.
