The Megger S1 meters (models S1-568/2, S1-1068/2, and S1-1568/2) are an advanced range of high-performance insulation resistance testers designed for use in high-voltage and high-noise environments, such as substations, distribution networks, and demanding industrial settings. These testers support test voltages of 5 kV, 10 kV, and 15 kV, providing accurate insulation resistance (IR) and a wide variety of additional diagnostic tests (including modes such as DAR, PI, DD, SV, ramp tests, and PDC) that enable a comprehensive evaluation of the dielectric condition of transformers, cables, switching equipment, and busbars. Thanks to advanced features such as adaptive filtering, noise immunity up to 8 mA, PI Predictor™ for rapid estimation of polarization indices, and RE>Act™ to optimize test repetitions, this range delivers stable and reliable results even under conditions of high electrical noise and switching transients. Connectivity via Bluetooth® or USB facilitates data export to platforms such as PowerDB or CertSuite for professional analysis and reporting.
Frequently Asked Questions
Which models are included in the Megger S1 series, and what test voltages do they offer?
The S1 series includes three models: S1-568/2 (up to 5 kV), S1-1068/2 (up to 10 kV), and S1-1568/2 (up to 15 kV), allowing you to select the appropriate test voltage based on the equipment or electrical asset being tested.
What test modes does the Megger S1 support besides insulation resistance (IR) measurement?
In addition to IR testing, these devices enable tests such as DAR (Dielectric Absorption Ratio), PI (Polarization Index), DD (Dielectric Discharge), SV (Step Voltage), ramp tests, and PDC (using software), providing a more comprehensive assessment of the insulation's condition.
What advanced features improve accuracy and reduce testing time?
The series includes features such as:
Adaptive filtering that dynamically suppresses noise interference for stable measurements,
Noise immunity up to 8 mA for reliable results in noisy substations,
PI Predictor™, which quickly estimates polarization index values, thereby reducing test time,
RE>Act™, which indicates when the insulation is ready to be retested without residual current errors.
How can test results be managed and exported?
The S1 meters feature Bluetooth® or USB connectivity, allowing results to be transferred to professional software such as PowerDB or CertSuite for detailed analysis, long-term storage, and the generation of technical reports without the need for manual data entry.
What are the benefits of using a remote control when taking measurements?
The remote control (via Bluetooth or USB) allows the equipment to be operated from a distance from the test area, which enhances the technician’s safety—especially in the presence of electric arcs or hazardous conditions—and improves efficiency during long measurement sessions.
