bc hydro voltage tolerance

Even when huge power bills are racked up and get paid, there's little the power company can do about the grow ops, because privacy laws keep it from tipping off the cops about suspicious power usage.

BC Hydro nor any of their employees or agents shall be nor become the agents of the Customer in any manner howsoever arising. 1885 Clements Rd, Unit 218 The primary causes are switching events and lightning, either direct strike or induced current. BC Hydro and FortisBC are the two largest utilities providing services to B.C. This means that care is needed by customer's, when selecting or specifying equipment essential to the proper functioning of their processes, to ensure that their facility exhibits a desired level of tolerance to expected PQ disturbances. The equipment must, as a minimum, be able to continuously operate without interruption at voltage levels associated with the "Unaffected Region". TSC Appendix 2 specifies that “All Equipment shall be able to withstand capacitor switching surges that transiently increase voltage to twice normal levels. Also, on a three-phase network without a neutral conductor or without load connected between line and ground, the values of the 3rd and 9th harmonics may be much lower than the compatibility levels, depending on the unbalance of the system.Note: The Canadian deviation consists of revised compatibility levels for the 3rd, 9th, 15th, and 21st harmonics orders; other values remain unchanged.

a)   IEC 61000-4-11 & -34:  These standards define the setup, equipment requirements and test methods for characterizing equipment immunity to PQ disturbances such as voltage sags, momentary interruptions and voltage variations. "Unfortunately there are cases where there are grow operations taking place where hydro is being paid for, but we are unable to provide RCMP with that information," said Elisha Moreno, a spokesperson with the utility.

This can occur in any combination of phases.​, A momentary increase of voltage magnitude relative to the nominal or pre-event voltage magnitude, characterized in terms of magnitude and duration. Pickering, ON h�bbd``b`� $[A�-�`V�4�w%�P�$��@b�@��7�(_���Ȩd100C�g��` �- A very brief (< 1 cycle) fluctuation in the magnitude of voltage. ​A long-duration reduction of voltage magnitude relative to nominal or pre-event voltage, characterized in terms of magnitude and duration.This can occur in any combination of phases. Recommended Type l and Type ll voltage sag immunity test levels (IEEE Std 1668-2017), Recommended Type lll voltage sag immunity test levels(IEEE Std 1668-2017). Clearances from both existing BC Hydro high voltage overhead conductors and pole-mounted dielectric liquid-filled transformers to any buildings must be also evaluated for conformance with the relevant provisions of the BC Hydro guidelines and standards. Utilities Commission (BCUC).. ​Repetitive or sudden fluctuations of voltage magnitude that results in variations in light intensity from electric luminaires, particularly incandescent lighting, perceptible to the human eye as “flicker”.

​Planning Level:Short-term flicker Index (Pst):HV: <= 0.8MV: <= 0.9Long-term flicker Index (Plt)HV: <= 0.7MV: <= 0.6Compatibility Level for LVPst <= 1.0Plt <= 0.8. Fax 905-686-1078 Table 1 below provides a brief description of these indices along with applicable industry standard(s) that Hydro One relies upon to govern their characterization. residents, and are regulated by the B.C. All of these disturbances can impact a facility to an extent that depends on the sensitivity of equipment and/or processes at the facility.Each of these basic categories has indices associated with it that are quantified in accordance with accepted industry protocols such that they provide a foundation for characterizing delivered power quality in a consistent and unambiguous manner. This means that care is needed by customer's, when selecting or specifying equipment essential to the proper functioning of their processes, to ensure that their facility exhibits a desired level of tolerance to expected PQ disturbances.There is industry wide evidence indicating that a large majority of costly process disruptions experienced by industrial processes are a result of the equipment or its controls responding undesirably to voltage sags – some resulting from events occurring on the utility delivery system and others originating inside the facility itself.

Service voltage requirements are tighter than utilization voltage as the standard allows for some voltage drop within a facility. naturally caused events or catastrophic equipment failures) or due to certain switching operations inherent to normal power system operations. BC Hydro's Moreno says the mail-out campaign costs just pennies per customer, and is worth the effort to stop the losses to pot growers stealing power. Source: IEEE Std 519-2014 Recommended Practices and Requirements for Hamonic Control in Electrical Power Systems. The provincial utility says it's losing millions of dollars because pot growers steal electricity, often by bypassing the power meters. ​CAN/CSA-C61000-3-7CAN/CSA - C61000-2-2 Flicker severity is measured in accordance with CAN/CSA 61000-4-15.
