Insulating oil in electrical power apparatus serves two primary roles, as an insulator and a coolant. As an insulating liquid, oil’s most important property is a high dielectric strength and as a cooling liquid, a low viscosity is paramount. The principal nemeses of insulating oil are oxidation, contamination (particularly moisture, which tends to lower the dielectric properties of insulating oil), and excessive temperature. These enemies are managed through design, regimented installation processes and prudent operation of the oil-filled power apparatus. At all stages of a power asset’s life, testing must be conducted to evaluate the condition of the insulating oil. In fact, for some assets, it can be argued that the oil is tested more frequently than any other component.

UL 746A -
National Technical Systems
The High Voltage Tracking Resistance (HVTR) test method is used to assess the susceptibility to tracking of insulating materials that are exposed to high voltages outdoors. Insulators installed in the open are often at the mercy of humidity. Their electrical insulation properties can deteriorate to such an extent as a result that tracking paths are formed on the insulator surface. This test determines the tracking resistance that defines the dielectric strength of the insulating material surface and the maximum allowable leakage current (tracking).

The DC Hi-Pot test is an important part and parcel of the electrical safety tests mandated by standards organization world-wide. More than 80 per cent of faults in electrical and electronic systems are due to weak insulation caused by environmental factors such as dirt, grease, temperature stress, humidity, etc that affect the dielectric strength of the insulation material.

LXinstruments GmbH
The hipot test (high potential test) or dielectric withstand test, is used to determine the insulation and dielectric strength. It is carried out on modules, devices and systems of protection class I + II. In this test, the insulation of the test object is subjected to greater stress by the high voltage than in normal operation. It is determined whether the insulation of all current-carrying conductors, as well as the safety distance to the enclosure, is sufficient and complies with the legal requirements under normal operating conditions.We will be happy to assist you with any questions or solutions to problems.You will find a large selection of high-voltage testers in our comprehensive shop.Questions? We are always at your disposal.

ITS-9050 -
Innovative Technical Systems
The Innovative Technical Systems ITS-9050 Detector is a sensitive, harmonic mixing detector designed to measure millimeter-wave free-space radiation. It is ideal for measuring radiation patterns of antennas inboth the near and far-field. The ITS-9050 employs a free-running dielectric resonator oscillator (DRO) and an integrated harmonic mixer with a waveguide RF input that either connects directly to a circuit under test or to an antenna for radiation detection. The resulting IF is amplified and detected by an IF log-detector that drives a front panel LCD voltmeter to provide an indication of signal strength. A DC output voltage from the log detector is available on a BNC connector to drive external data acquisition instrumentation. Also, a sample of the IF output is provided for measurement on a spectrum analyzer.
