Construction Drone

Fingertip Cost Savings for T&D Industry Infrastructure

The surge of interest in construction drones to be used in the T&D infrastructure construction process is growing and advancing in leaps and bounds as the North American utilities companies realize the multi-potential uses of this technology. Not since the introduction of the mobile computer devices to the utilities sector has there been so much recognizable potential for this technology, in so many different capacities. The drone world has begun to turn its eye to the electrical construction industry regarding the building of power plants to electrical substations to distribution systems, and the potential for savings and improvements is staggering. The drone technology for surveying, safety, security and even resource tracking is now available, literally at ones fingertips.

T&D Construction Booms

In 2015 North American Electric T&D industry exceeded $49 billion on T&D construction projects from power plants to electrical substations to distribution systems. That is higher than any of the previous years since the 2009;

Regulatory requirements and incentives, fueled by the need to improve the reliability and capacity of the North American T&D network, provides an opportunity for utilities and developers to make substantial investments to replace, upgrade, and expand new and existing T&D infrastructure.

T&D Infrastructure Overview

Power Plant - Electricity is generated at the power plant at a relatively low voltage
High Voltage Transformer – Voltage is increased by transformers from hundreds to hundreds of thousands of volts for transportation over long distances.
Transmission Lines – High voltage transmission lines carry power from the power plant to the substations.
Transmission Substations – Contain high voltage switches allowing the connection, isolation or maintenance of high-power lines.
Distribution Substations – Contain transformers that “step-down” reduce the high voltage power to a lower level for distribution to the end user.
Distribution Systems – Main/primary power lines and low voltage secondary power lines deliver electricity via overhead or underground wires/cables to the end user.
Service Connection – Power line that connects the electricity to a meter at the end users location.

Construction Drones

Companies like 3D Robotics, DroneDeploy and Kespry to name a few, offer “smart construction drones”. As an example of the seemingly endless technology, Kespry’s drone the Kespry 2.0 can fly over 150 acres in 30 minutes providing aerial data. Even self-built and off the shelf drones have the capability to provide an astounding range of information with the use of basic attachments and software.

Listed below are a few of the technically advanced attributes which the new “smart drones” are capable of producing.

Site Mapping with Drones

completing accurate 3D models of existing and new structures
overlays of the original plans with the recorded data
accurate topographical maps
temporary roads and structures can be planned in advance and plotted into the 3D maps

Materials & Inventory Controls

determine the size of stockpiles like gravel, lumber, and rebar
identify equipment and machinery on site
inventory updates, useable materials automatically assessed and equipment requirements calculated
provides accurate data for the project manager
eliminate unnecessary spending
real time information
real time and forecasted business decisions.

Further Features

cloud connectivity
monitor progress (on more than one project if necessary)
show progress to clients
keep extensive 3D records of the changes on a day by day basis
structural inspection
authenticate work done from office or home
security service; perform automated patrols of a defined area, recording security footage (even utilizing infrared cameras)

There are many construction industry security services and construction industry management services which are now realizing the advantages of employing the use of drones in the building of power plants to electrical substations to distribution systems. Basically one construction drone can perform most of the features mentioned above without the requirement of specialist equipment. Their software handles the raw data and translates it into meaningful and actionable information throughout all aspects of a T&D infrastructure construction project and post project. The cost savings and time savings compared to traditional methods will be staggering and very hard for an electrical utilities company to ignore.

Evluma Launches Line of Post Top Globes to Complement LED OmniMax

March 12, 2020, Renton, WA…Street and area lighting manufacturer Evluma, announces the release of a new globe accessory line, OmniMax Lighting Solutions (OLS) to complement their OmniMax family of LED replacement lamps. OLS is a custom, curated selection of spherical and acorn style globes for decorative streetlights. The OmniMax is a Bluetooth-connected, screw-in replacement lamp for use in decorative post top globe and acorn lights. The release of a globe line to complement the OmniMax is designed to make the HID to LED conversion and maintenance process easier for Evluma customers.

Customers executing a retrofit project can conveniently purchase a replacement globe at the same time they purchase the OmniMax. “The wide variety of styles and materials offered means that we can typically provide a customer with a globe that matches an older style,” said Marketing Director, Cathleen Shattuck. “Customers can refresh globes simultaneously with OmniMax installation to save on labor, or if they suddenly discover damage to individual light fixtures, we can quickly provide them with a solution. Our high level of customer service means we are well-adapted to quick turnaround on orders of any size, keeping the process convenient and low cost.”

Using OmniMax, municipalities, utilities and electric departments converting post top fixtures from HID to LED can do so in under 5 minutes a fixture. The OmniMax is available in both Premium and Standard models. Premium models are Bluetooth-enabled and are compatible with Evluma’s wireless control application, ConnectLED.

Parallel Resonant AC Test Sets

High Voltage, Inc. is an American test equipment manufacturing company located in rural Copake, NY. We are known for high quality, easy to use equipment and for our commitment to providing the best customer and product support in the industry.

As we matured we expanded into larger products. Cable fault locators (thumpers) as well as higher power ac (HPA) dielectric testers as might be used in a factory environment. Our HPA line of ac testers are available with outputs up to 300 kV ac and power levels up to 40 kVA and can be customized with various levels of control sophistication.

Our new PAR line of ac dielectric testers are designed to meet the needs of those who need power levels up to 250 kVA, to be able to test their highly capacitive test loads. Using ac resonant technology outputs of 50 kV at 5A (for example) are possible with an input of only 230 v, 90 A. That is an input of 20 kVA for an output of 250 kVA. (Model PAR-50250FC5)

The PAR models consist of a control section and a high voltage section. While large, they are transportable by van or trailer for field work. The control section includes the input breaker, variable (motorized) input control, a PLC controller, and connections for controlling the hv section. The high voltage section is a steel tank with a phenolic output bushing. Inside this tank is a variable-core reactor in an insulating oil bath with an air space at the top to allow for thermal expansion.

The variable reactor looks similar to a transformer but has a moveable core that allows the inductance value to vary to match the capacitance of the load, thereby achieving resonance. This effectively cancels the load capacitance, as far as input power requirements are concerned. Once in resonance, the input voltage is increased until the desired output voltage level is achieved. For a capacitive load that must be tested at power frequency the PAR reduces power requirements, as well as test equipment size by one tenth to one thirtieth, compared to a test transformer.

The HVI PAR family of resonant as dielectric testers are perfect for power frequency testing of power cables, rotating machinery, bushings, instrument transformers, transformers, shunt reactors, and many other products.
