26
Q

Loss of electricity supply for small amounts of time that result from the fuses opening and closing again as a result of the voltage changes not large enough to completely shut down the power

A

27
Q

The management of trees and vegetation on the overhead lines following a survey or assessment of the problems and scheduling maintenance before vegetation causes any interruptions

A

Preventative or proactive maintenance

28
Q

Management of trees and vegetation in response to interruptions caused by vegetation

A

Reactive or corrective maintenance

29
Q

A method to minimize Tree-caused outages by conducting a detailed analysis of the system, vegetation conditions, outage history, infrastructure, and other factors, and identifying a range of preventative maintenance tasks that have the potential to provide greater reliability and cost efficiency then pruning and removal alone

A

Reliability-centered management (RCM)

30
Q

Area of land under and just adjacent to overhead conductors over which the utility has a negotiated right to enter and maintain vegetation when required

A

Right-of-way (ROW)

Q

A single or multi blade arrangement that rotates horizontally and cuts or shreds the education

A

Rotary cutting head

32
Q

A measure of the number of interruptions that occur on a utility’s system

A

33
Q

Directing herbicides specifically at target (undesirable plants) leaving desirable plants untreated so that they remain

A

Selective application

34
Q

Herbicides that are predominantly effective on certain plant species, typically the undesirable ones, leaving low growing desirable plants unaffected

A

Selective herbicides

35
Q

A method of applying herbicides or tree growth regulators to trees through the soil by excavating a shallow trench in the soil around the base of the trunk and pouring the compound into the trench

A

Soil drench application

36
Q

A method of applying herbicides or tree growth regulators to trees through the soil via injection directly into the root zone

A

Soil injection application
