KI-16171 Automatic High Voltage Insulating Oil Tester |
| Test Method The majority of high-voltage transformers, cables, switchgears, transducers, capacitors, and rectifiers use insulating oils for insulating electrically live parts and to carry off thermal energy. The quality of the insulating oil must be checked at regular intervals to ensure a long equipment service life. The most important requirement of an insulating oil is a high dielectric strength. Determination of the dielectric breakdown voltage of insulating oils provides an early detection method for any reduction in the insulating properties. Features and Benefits • Conforms to ASTM D877, D1816 and related test specifications • Suitable for all insulating fluids • Fast cut-out of the high voltage immediately after oil dielectric breakdown • Overtemperature protection system with power cut-out |

| KI-16171 Automatic High Voltage Insulating Oil Tester The Koehler Automatic and Semi-Automatic High Voltage Insulating Oil Testers perform the determination of insulating oil dielectric breakdown for both single and multiple tests. The apparatus consists of a frame housing with LED display, sample compartment with indirect illumination, and a motor-driven rotary table. The measuring electrodes are swiveling and arranged eccentrically with respect to the axis of the table, enabling an easier cleaning and dispersing of any combustion sediments by the rotary motion. A thorough mixing of the oil is achieved by a magnetic rod inserted into the testing vessel. Contactless drive is provided by a small motor with an additional magnet below the lift. For operator security, the sample chamber is closed by a perspex door with an interlocking switch. A special safety feature locks the start button in case of improper electrical grounding. Specifications Conforms to the specifications of: ASTM D877, D1816; IP 295; FTM 791-5702; NF C 27-221; IEC 156; VDE 0370 Voltage Between Electrodes: 0-60, 0-75, or 0-100 kVrms Voltage Increase, adjustable: 0.5, 2, 3, or 5 kV/sec Switch-off Time: < 100µsec Display: 7 segment LED Included Accessories Epoxy Test Cup, 400mL One Pair of Electrodes, spherical dome shape Setting Gauge 2.5 / 10mm Fuses (2) Electrical Requirements 115/230V 50/60Hz Dimensions lxwxh,in.(cm) 17.5x19.75x13.5 (44.5x50x34.5) Net Weight: 99 lbs (45kg) |
