AC PROTECTION WITH POWER METERING

**NEW PRODUCT**

The LS Executive Series provides rugged surge protection at the main service panel along with new onboard, revenue-grade power and energy meter. Each phase is guarded by multiple redundant protection paths – reassuring when sensitive equipment’s continuous operation is at stake. Twenty-year, no-nonsense warranty (five-year warranty on power meter); free protection modules for life. Series features mix-and-match options for a customized protector at stock prices. 

Popular Applications Include:

  • Monitor power and energy use of an entire facility or of a single piece of equipment.
  • Monitoring system voltage and current (up to 32,000A) as well as other parameters. 
  • Ensuring accuracy in utility billing and crediting by allowing users to compare kilowatt-hours.
  • Alerting users if a predetermined energy use or electrical parameter is outside of the user’s acceptable region.
  • Energy monitoring in building automation systems.
  • Energy Management – track where and when energy is used in an industrial plant or building.
  • Cost allocation (how much does a particular process or equipment cost to run?)
  • Industrial Monitoring – track usage of assembly lines or equipment/processes.
  • Commercial submetering.
  • Renewable energy – monitors power exported to grid from the renewable energy source and power imported from grid.

Field Notes from Dion Neri, MCG Chief Engineer

September 2015

Hi Everyone,

Today MCG Surge Protection visited a highly regarded studio in the New York metropolitan area to perform a site survey at a building that is experiencing equipment damage due to lightning and other surges. We spent most of our time on the 8th floor where the equipment that controls the tower lights is located.  Surveying this facility was exciting, as the facility is a very prominent part of the Brooklyn skyline.  

LED lights illuminate the towers at night, and they are very impressive, but they also attract lightning since they extend 90 feet into the sky. The towers consist of vintage World War II radio towers, now repurposed to depict a lit-up bridge.   

To protect the systems on the that control the lights, we recommended one modular AC protector, Model 160M, at the AC distribution panel powering the light controller, several AC power line units, PT80s, to protect the individual outgoing AC lines exiting the controller, Ethernet protectors, for the communication ports, and the DLP-37A, a modular 28 wire multi-wire data line protector, for the communication lines exiting an external repeater fed from the controller.  The facility ordered and installed the MCG units within the week.

It is great to have MCG protecting this prestigious facility. 

Sincerely,

Dion Neri
Chief Engineer

THE CRITICAL NEED FOR SURGE PROTECTION
IN ELECTRIC CAR CHARGING SYSTEMS

 
 

The Critical Need for Surge Protection in Electric Car Charging Systems

By Dion Neri, Engineering Manager, MCG Surge Protection, Inc.

Deer Park, NY May, 2015

Electric Cars are inherently more reliable than the gasoline ones that they are replacing. So, anyone who purchases one of these vehicles can reasonably expect years of trouble-free transportation. Typically these cars are driven in the daytime and electrically charged at night.

However, these reliable new vehicles are subject to severe damage by transients while they are being charged. These transients may be the result of a nearby lightning strike, utility failures, or human error. Transients can do severe damage to the charger, the batteries, and other parts of the car.

Damage to the vehicle is not the only cost issue for the owner - there is also the hassle of having it towed to the dealer for repair, which can result in days of lost use. Even if the damage is covered by its warranty, and it may not be, an event such as this is a great inconvenience.

The best way to minimize the risk is to install AC Power Line Surge Protectors (SPD) especially designed for this application by MCG Surge Protection. MCG’s PT series or M series are typically used in these applications, specifically a PT80-120T-BB or 125M-120T-A.The surge protectors come with a 20-yr, “No Nonsense” warranty and free replacement modules, where applicable, for life.

Another benefit of using surge protectors is that surges generated by the car’s electric motors will be prevented from back feeding to the service panel, and damaging computers, cell phones/tablets (while they’re charging), HDTV, HVAC controls, and other sensitive electronic equipment at the residence. The protectors include low-frequency filters that minimize low-frequency noise interference in electrical systems. Surge protectors are cost-effective and easily installed by licensed electricians. Installing surge protection devices (SPD) ensures that all of your electronics equipment operates more reliably.

MCG has been manufacturing surge protectors for over 48 years. They also protect chargers used with forklifts, golf carts, and other similar devices. For additional information, please visit www.mcgsurge.com, or contact Dion Neri, at dion@mcgsurge.com.
