ANSI C12.20 0.5%
ANSI C12.20 is a standard for electric meters, particularly focusing on the accuracy of digital and mechanical meters used in residential and commercial settings. The "0.5%" specification refers to the allowable margin of error in the meter's readings.
-
backfeed
When a renewable energy system (such as solar) produces more power than the location demands, and power is pushed back onto the grid rather than being drawn.
-
big-endian
Big-endian is a byte order in which the big end -- the most significant value in the sequence -- is first, at the lowest storage address.
-
Cat III
Over voltage Category III refers to a classification used in electrical systems, signifying equipment that is part of a building's fixed wiring installation, like distribution boards, socket outlets, and permanently connected appliances, where a higher level of protection against transient voltage surges is required compared to standard household plugs; essentially, it applies to equipment within the main electrical distribution panel of a building, not directly at the utility source.
-
CAT IV
Category IV is the highest overvoltage category and applies to equipment used at the origin of the installation; that is, connected directly at the utility side. Examples are distribution panels, utility-grade transformers, and meters.
-
CE
the CE mark indicates that a product complies with EU regulations for safety, health, and environmental standards and is allowed to be sold within the European Union and other associated countries.
-
CSA 22.2
CSA 22.2 is a set of safety standards for electrical and electronic products in Canada.
-
Date & Time when recording started
Date and Time when recording started (DATWRS) refers to a setting on the eGauge that defines meter epoch. It can be found in the 'General Settings' page of the meter setup.
-
FCC Title 47
FCC Title 47 CFR Part 15, Subpart B, Class B ensures that home electronics don't emit too much interference, protecting the functionality of other devices in residential environments.
-
IEC/UL 61010-1
UL 61010-1 is a safety standard for electrical equipment used in measurement, control, and laboratory settings. It ensures the equipment is safe to use, protecting users from electrical hazards, mechanical risks, overheating, and other potential dangers. Equipment that meets this standard has been tested to ensure it won't cause harm during normal use.
-
IEEE/ANSI C57.13
IEEE/ANSI C57.13 is a safety and performance standard for instrument transformers, which are devices used in electrical systems to measure and monitor high voltage and current. The standard ensures these transformers are accurate, safe, and durable, protecting both people and equipment in the power industry. It covers everything from the construction of the transformers to the testing and environmental conditions they must endure, making sure they meet the necessary requirements for safe and reliable operation.
-
leg
A single voltage line typically referring to a particular line input of the eGauge, such as L1, L2 or L3. Leg and phase may be used interchangeably.
-
little-endian
A byte order which stores the least-significant byte at the smallest address.
-
phase
A single voltage line on an electrical system. There are at maximum three phases on a system or panel.
-
phase mismatch
When applying Current and Voltage readings from different phases against each other to calculate power the result will be incorrect.
-
RoHS
Restriction of Hazardous Substances in Electrical and Electronic Equipment. It's a set of European Union (EU) rules that limit the use of hazardous substances in electrical and electronic products to protect public health and the environment.
-
single-phase
Circuit consisting of two conductors; either two voltage lines or a voltage line and a Neutral.
-
split-phase
Electrical service or panel containing two voltage lines and a Neutral.
-
thermowell
a protective housing for temperature sensors, such as thermocouples or RTDs (Resistance Temperature Detectors), in industrial applications. It's essentially a closed-end tube that is inserted into a process vessel or pipe, allowing the temperature sensor to be inserted into the thermowell. The main purpose of a thermowell is to shield the temperature sensor from process fluids, chemicals, and physical impacts, thus ensuring accurate and reliable temperature readings over time.
-
three-phase
Electrical service or panel containing three voltage lines, with or without a Neutral. A three-phase Wye has a Neutral, a three-phase Delta does not.
-
UL: 2808
a safety standard set by Underwriters Laboratories (UL) that specifically pertains to energy monitoring equipment, particularly open-type current transformers (CTs) used for field installation in applications like submetering, distribution panels, and industrial control equipment; signifying that a product has been tested and certified to meet the safety requirements outlined in the UL 2808 standard for accurate current measurement and safe operation.
-
UL 61010-1
UL 61010-1 is a safety standard for electrical equipment used in measurement, control, and laboratory settings. It ensures the equipment is safe to use, protecting users from electrical hazards, mechanical risks, overheating, and other potential dangers. Equipment that meets this standard has been tested to ensure it won't cause harm during normal use.
-
UL Recognized
"UL Recognized" means that a component has passed UL’s safety testing for a specific application.
