Revenue protection is an important part for any business that operates over an extended period of time. When it comes to the commercial and indultrial (C&I) market, it is imperative to maintain peak performance installations at all times. Undetected problems in the C&I market can result in exponential revenue loss for every month that a problem goes unresolved.

The revenue loss equation is quite simple:

Energy consumption x Rate x Error % x Number of months = Revenue Lost

The potential risk for a customer installations range from simple wiring problems to defective installations, faulty equipment and even tampering.

As opposed to damage control, routine inspection or preventive maintenance has two positive impacts,

  • Allowing utilities to detect these issues before they ever impact their ROI
  • Providing the baseline to analyzing future test results.

Addressing quality concerns early in transformer-rated installation by means of preventive maintenance is a good approach to revenue protection.

Why testing from the meter base?

A site tester that connects directly to the meter base minimizes any safety risk and human error that could result in lost revenue. In fact, the tester reads exactly what the meter sees, tests the entire system, and gets real data in real time straight from the meter base. All these features contribute to improved performance and further reduce revenue loss.

 

No need to trade the ­performance of the installati­ons for team ­productivity.

It is in the utilities’ best interest to choose a portable site tester that guarantees them a fast, effective response and reliability in order to optimize their technicians’ productivity and maximize their ROI.

Choosing the right site tester to perform the necessary inspection is crucial for identifying the sources of revenue loss and being able to fix them adequately. But it also has other benefits.

How to Improve ROI by Testing the Accuracy of an AMI Meter?

How to Improve ROI by Testing the Accuracy of an AMI Meter? 150 150 Probewell
[vc_single_image image=”9331″ img_size=”full” alignment=”center”]

Nowadays, electric utilities expect AMI electrical grids and MDMS solution to provide advanced data analytics so they can make informed data-driven decisions to achieve operational efficiency (hardware and services).

Customers often distrust new technologies and are reluctant to adopt them. It is up to the utilities to reassure their customers as part of their onboarding process and a good way to do this is to keep them informed by making the process as transparent as possible.

When it comes to AMI efficiency, the key factor is the accuracy of the meters, thus the reliability of the data they aggregate.

When deploying or maintaining an AMI grid, some discrepancies may be noticed in the data after the initial transition. For instance, the data collected from a mechanical meter may differ from the data collected from a digital meter, which is often more accurate, naturally prompting clients to question their bill.

Verifying the accuracy of the meter

 

The WT Series wireless tester help building a better customer’s experience, by allowing sharing of traceable test reports as part of the onboarding process and facilitate the adoption of the AMI technology and finally, improve your ROI without affecting your bottom line.

Our meter tester enables a wide range of testing options. It allows the operator to assess the electric meter on site and in real time, checking the accuracy of the meter’s reading and performance. The typical accuracy is ± 0.02%, to ensure fair billing.

It is possible to perform a Quick Test, using the Probewell Connect application to quickly assess the accuracy of each meter and keep a traceable report of the meters accuracy readings, before and after the transition (as found and as left reporting). The Quick Test runs a series of sub-tests (for each of the loads: HL, PF and LL and it calculates the weight average), in a single operation.

The test results are securely stored within the unit and includes the meter ID, time-stamped and geolocation data for traceability purpose. The test reports can be shared by e-mail, right from the operator’s mobile to the customer and the utility’s customer service department for a follow-up.

Net metering:
Fostering a fair exchange between utility companies and their customers.

Mariana Napoli | Sales and Marketing Director | Probewell Lab Inc.

The US federal government requires utility companies to purchase surplus energy from independent producers.  Over 40 states have laws in place to ensure credit is given for this excess consumer generation. State regulatory agencies review the rates utilities charge retail consumers to ensure they are reasonable under their ratemaking jurisdiction.

 

Some utility companies still perceive Net Metering policies as lost revenue opportunities, but in most cases, Net Metering allows utilities to better manage their peak electricity load as well as reduce the strain on the distribution system.

[vc_empty_space][vc_message icon_fontawesome=”fa fa-quote-left”]According to the Statista.com  site   , statistics collected between 2010 and 2019, show that the number of customers turning to alternative energy sources and purchasing power generation equipment such a wind turbine and photovoltaic systems, rose from 155,921 to 2,438,193* representing a 156.3% increase per year.[/vc_message][vc_empty_space]

Measure the power they export back to the grid

Probewell | WT Series | Meter testing | MT-1/WT3

In some case, consumers will produce more electrical power than they consume during peak generating conditions. Net Metering allows these customers to measure the power they export back to the grid, to save on their future electrical bills and benefit the environment by generating renewable energy.

 

Bills based on actual meter readings will reflect the difference between the value of the electricity injected into the grid and the value of the electricity  customers   consumed from the grid.

 

In order to determine how much power is fed back and to ensure a fair exchange between the utility companies and the customers, an accurate meter reading of both the forward and reverse power flow is critical.

[vc_empty_space][vc_message message_box_color=”grey”]Over time, the calibration of the sensors in bidirectional meters may drift one way or another, preventing an accurate reading of the forward or reverse power flow, resulting in loss of revenue for either the customer or the electrical utility provider.[/vc_message][vc_empty_space]

This requires a solution that fits seamlessly into the daily workflow.

 

To prevent this, a simple routine maintenance schedule should be implemented that includes a reverse power flow test. This requires a fast and easy-to-use testing solution that fits seamlessly into the daily workflow.

Why You Should Care about Ratio, Burden and Admittance Testing on Transformer-Rated Installations

Why You Should Care about Ratio, Burden and Admittance Testing on Transformer-Rated Installations 150 150 Probewell
[vc_single_image image=”9153″ img_size=”full” alignment=”center”]

Keeping transformer-rated installations within the operating range recommended by ANSI plays a critical role in the financial health of both utilities and their customers.

Current and potential transformers rarely have problems, but they can arise, whether due to magnetization of the CT over time, faulty wiring, a closed CT shunt, corrosion on the switches or a bad meter insertion at the socket. When these problems occur, costs quickly add up, and not just to fix the hardware issue.

[vc_empty_space][vc_message icon_fontawesome=”fa fa-exclamation-circle”]It’s imperative that these types of issues be promptly caught and resolved or the utility could lose several thousands in revenue every month that the problem remains undetected.[/vc_message][vc_empty_space]

Not to mention the hassle when it comes time to announce additional billing for backlogs to the customer, or an upward rate adjustment (sometime up to 300%) in order to rectify the situation.

 

On the other hand, when assessing an installation in response to a high bill complaint, utility companies could discover that they have been over charging their customers. When this happens, damage control is needed. But even after the utility fixes the problem and negotiates the amount to be reimbursed to the customer, the situation will have eroded trust in the company’s services and tarnished its reputation.

 

These types of problems can easily be detected when servicing a transformer-rated installation by performing  CT/PT ratio, burden and admittance tests.

[vc_empty_space]

Better safe than sorry!

 

With good planning, you can manage the risks that stem from these challenges. For instance, performing a full assessment, including ratio, burden and admittance tests on transformer-rated installations upon deployment as part of a routine quality assurance check. Then be sure to include it in your yearly maintenance plan, which is already mandatory in some states. To do so, an easy-to-use testing solution that fits seamlessly into your usual maintenance routine is vital…
