Megger DELTA 4110 / 4310 12 kV Insulation Diagnostic System
The DELTA4000 is used for shop and field testing of high-voltage electrical insulating systems at test voltages up to 12 kV. Test results can be used to evaluate the nature and quality of electrical insulating materials and manufacturing processes to reveal contamination, fractures, punctures, and other defects that accompany the aging of insulation. The test set comprises of a control unit, a high-voltage unit, cables, and canvas carrying bags.
Tests are made by measuring the capacitance and dissipation factor (power factor) of a specimen. The values measured will change when undesirable conditions exist, such as moisture on or in the insulation; presence of conductive contaminants in insulating oil, gas or solids; presence of internal partial discharges etc.
The test set measures insulation properties in high-voltage power equipment such as transformers, bushings, rotating machines, cables, circuit breakers, capacitors, surge (lightning) arresters etc. In addition, the test set can also measure transformer excitation current and transformer turns ratio (with optional TTR capacitor).
The DELTA4000 Series is designed for condition assessment of electrical insulation in high voltage apparatus such as:
- Transformers
- Bushings
- Circuit breakers
- Cables
- Lightning arresters
- Rotating machinery
The test set is designed to provide a comprehensive AC insulation diagnostic test. The high power variable frequency design generates its own test signal independent of line frequency quality and the hardware design uses the latest technology available for digital filtering of the response signal. As a result, the DELTA4000 Series produces reliable results and stable readings, in the shortest time with the highest accuracy, even in high interference substations.
The DELTA4000 Series operates with PowerDB software for automatic testing and reporting or with Delta Control software for real-time manual testing.
Measurements include voltage, current, power (loss), tan delta, inductance, power factor and capacitance. The test results are automatically stored in the computer and can also be downloaded directly to USB storage or a printer.
