Banair
This is a high specification tester that will measure many cable parameters. It measures cable resistance very accurately using the Kelvin 4-wire method. It also tests for shorts between pins at a low voltage. The next test is to measure insulation between connections at a higher voltage. This is carried out at up to 1500 Volts DC with resistances of 10 to 500 Meg ohms.

New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.

ASTM D257 -
National Technical Systems
These test methods cover direct-current procedures for the measurement of dc insulation resistance,volume resistance, and surface resistance. From such measurements and the geometric dimensions of specimen and electrodes, both volume and surface resistivity of electrical insulating materials can be calculated, as well as the corresponding conductances and conductivities. These test methods are not suitable for use in measuring the electrical resistance/conductance of moderately conductive materials. Use Test Method D4496 to evaluate such materials. This standard describes several general alternative methodologies for measuring resistance (or conductance). Specific materials can be tested most appropriately by using standard ASTM test methods applicable to the specific material that define both voltage stress limits and finite electrification times as well as specimen configuration and electrode geometry. These individual specific test methodologies would be better able to define the precision and bias for the determination.

TTC-1 -
Lisun Electronics Inc.
It is according to IEC60695 and IEC60112 (GB4207), the Tracking Test Chamber TTC-1 is intended for determining the degree of protection against formation of conducting paths in solid insulating materials, due to the electric stress and electrolytic contamination of the surface. This method simulates tracking currents on insulation material by providing drops between electrodes. During the process of normal use, insulating material may be exposed to moisture and dirt, if conductive, may cause stress and fire hazard.

Laycock Systems
Crown high voltage, transformer type hipot insulation testers are safe, easy to use for quick, positive determination of grounds, shorts, and broken wires in motors, transformers and other low voltage equipment or wiring systems. A turn of the selector switch gives a selection of seven voltages; 500, 1080, 1250, 1500, 1750, 2000 or 2500 volts calibrated to +/- 5% accuracy; NEMA recommendation for insulation test is twice normal voltage plus 1000 volts. Since this instrument has a capacity of 2500 volts, it readily accommodates all normal requirements.
