There are nine different models in the new TPMP Series three-phase motor protector line. Users can choose protection from phase sequence problems to phase loss and out-of-balance issues, the ...

Voltage unbalance can be a common steady-state power quality problem that is harmful to 3-phase electric motors. The condition can cause overheating and insulation damage. The cost of damage to motors ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...
