6.7.5 High-voltage surge arresters

Use a high-voltage surge arrester to protect the motor against
lightning and switching surges.
Lightning voltage surges in power lines are caused when lightning
strikes somewhere in the area.
Switching surges are caused by the opening and closing of
switches on the main high-voltage distribution power lines.
Install the correct voltage-rated surge arrester on the supply side of
the control box. See the figures below. The arrester must be
grounded in accordance with the National Electrical Code/
Canadian Electrical Code and local codes and regulations.

To MS motor

The warranty on all three-phase submersible motors
becomes void in the following cases:

•

The motor is operated with single-phase power through a phase
converter.

•

Three-leg ambient compensated, extra quick-trip overload
protectors are not used.

•

Three-phase current imbalance is not checked and recorded.

•

High-voltage surge arresters are not installed.
