33. Highly Fluctuating Loads

33.1  A Customer’s equipment shall not create unusual voltage fluctuations. Harmonic distortion or other disturbances on the PUD’s system that exceeds the limits specified in IEEE Standard 519 or exceeds the voltage variation limits specified in ANSI Standard C84.1 may require the Customer to pay for the installation of corrective equipment. If the Customer delays or refuses to install adequate equipment to correct the situation, Electric Service may be disconnected in accordance with Section 17.

33.2  The PUD reserves the right to refuse to serve highly fluctuating and intermittent loads, including but not limited to arc welders, large motors, x-ray machines, which may cause interference or disturb the quality of service to other Customers.
