The Megger S1-568/2 5KV insulation testers are known worldwide for their rugged dependability, long service life and accurate, reliable measurements. The extensive range of models means that there will always be a perfect match for your requirements. One common feature across the whole range is the Megger, �no compromise� approach to safety. The Megger level of safety will always go further than simply complying with the relevant safety standards
The Megger S1-568/2 models ia the ideal solution for customers requiring higher capacitance charge rates (testing long cables), working in electrically noisy environments (e.g. transmission voltages), remote operation, or data storage,
Prductivity and accuracy is a focus of the Megger S1-568/2, offering rapid charge batteries and operation from an AC source when the battery is flat or low. An intuitive user interface ensures no lost time remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and a large backlight display which enables multiple measurement information to be displayed simultaneously. A graphical quick start guide is provided inside the lid of each model to assist first time users and has QR code links to the online User Guide.
Measurement accuracy is of high importance for any insulation resistance measurement. It is particularly important to ensure that the accuracy is maintained up to higher IR values that are required by some applications. The Megger S1-568/2 provides an excellent �5% accuracy all the way up to 1 T? at 5,000V.
New Features
PI Predictor Function (PIP) The Polarisation Index test can be time consuming, with a 10 minute test (30 mins on 3 phase) and with multiple items to test, any time saved is a bonus. PIp does just that. The PI predictor function uses the first part of the IR curve to predict the rest at 5 minutes into the test. The PIp can start as early as 3 minutes into the test and will stop when it is confident in the prediction.
RE>ACT Test Mode This ground breaking feature will revolutionise the reliability of your measurements. When insulation testing it is essential that any re-absorption current from the insulation under test is fully discharged before starting the test. Remaining absorption current, depending on polarity, can result in IR measurements that are falsely high or low, with the potential to incorrectly pass any failing insulation. The RE>Act mode not only measures this reabsorption current but also provides an indication to the user of the impact it will have on the instruments� measurement range and accuracy.
Preconfigured diagnostic tests include Polarisation Index (PI), Dielectric Absorption Ratio (DAR) on all models. Dielectric Discharge (DD), Polarisation Depolarisation Current (PDC), Stepped Voltage (SV) and Ramp test.
The Megger S1-568/2 includes memory storage with time/date stamping of results, logging of data and recall of results to screen. A fully isolated USB interface or on-board Bluetooth� interface is used for safe transfer of data to software. The following options are available:
- Mobile app, browser based software: CertSuite Asset and testing and reporting software. See below for more details.
- PC based asset management software: PowerDB Pro, Advanced or the free Lite packages
