Electrical Testing

Low Tension (LT) Line and High Tension (HT) Line refer to the voltage levels of electrical power distribution systems.

LT lines are electrical power distribution systems that operate at a voltage level of 1000 volts or less. These are typically used for lighting and other small electrical loads within buildings and homes.

HT lines, on the other hand, operate at a voltage level above 1000 volts. They are used for transmitting large amounts of electrical power over long distances, and are typically found in the power transmission and distribution networks of utility companies.

It is important to note that HT lines pose a greater danger to humans and equipment compared to LT lines, as the higher voltage levels involved can result in serious injury or damage if proper safety precautions are not taken. As a result, HT lines require more robust insulation and protective equipment, and specialized electrical testing procedures to ensure safe and reliable operation.
