The maximum demand with regards to diversity is when an electrical device is running at its maximum capability. The diversity number is typically a percentage, so if a device is running at 80 percent diversity, it is running on maximum demand 80 percent of the time.
maximum demand load can be calculated as: # maximum demand=demand factor * Connected load or by # maximum demand = connected load * Diversity Factor Note: Demand factor and diversity factor are NOT same
Diversity factor is the ratio between sum of each individual maximum demand and the total maximum demand. There are several equipment with different connected load and its maximum demand in an industry. Each equipment maximum demand could be different and might occur at different times. A well estimated or measured diversity factor would tell as to what percentage of total maximum load would actually occur. Diversity factor is always less than 1. Diversity factor has to be obtained either by measuring the actual sum of each individual load and maximum demand or estimated and has relation to the transformer full load .
Commercial electrical customers are billed a demand charge as part of their electrical bill. The idea is that if the customer's peak instantaneous KW usage (demand) is high, the utility has to provide large enough generating and transmission capacity, which costs money. Controlling maximum demand lowers the electric bill, saving the customer money. The act of doing so is called peak shaving, and is usually accomplished by turning off non critical loads or providing onsite co-generation to reduce utility consumption to prevent a new peak from occuring.
Try to think of a diversity factor as similar to a noncoincidental load factor. If your thermostat phyically limits you to only using either heat or AC at one time, then you can simply use the largest of the two as your load factor. With diversity, think of a college campus environment. If you are in class then the odds are your TV, oven, microwave, etc back in your dorm are probably not being used. R, Bill
Non-coincidental loads refer to the electrical loads in a system that do not reach their peak demand simultaneously. In other words, these loads operate independently and at different times, meaning their maximum demand levels do not coincide with each other. This is important for energy management and system design, as it allows for more efficient resource allocation and can reduce the overall capacity needed for power generation and distribution. Understanding non-coincidental loads helps in optimizing the performance and reliability of electrical systems.

That depends on it's gauge, the lower the gauge the higher load it can handle.Another AnswerMaximum demand describes the maximum electrical load applied to a high-voltage (high-tension) electrical cable.
Demand load refers to the maximum amount of power that electrical equipment or systems require at any given time. For ranges with ratings of 15 kW, 14 kW, 10 kW, and 9 kW, the demand load would typically be the highest wattage rating during peak operation. However, in practice, demand load calculations often consider factors like diversity and load factors, which can reduce the effective demand load from the maximum rating. Thus, the actual demand load may be lower than the rated wattage depending on usage patterns.

An electricity board will be fixed some amount of load for consumer (industry or commercial) as per consumers requirement.That is maximum load or maximum demandAnswerA 'maximum demand indicator' (also called a 'thermal demand indicator') is a thermally-operated measuring instrument which indicates the maximum current supplied by a distribution transformer, from which that transformer's actual (rather than anticipated) maximum load can be determined. A distribution transformer is sized based on an anticipated load, resulting from an analysis of the loads to be supplied (taking into account after-diversity maximum demand), this instrument allows the actual maximum load to be compared with that calculated load, and this value should be less if the original analysis was performed correctly.
MAXIMUM DEMAND (M.D.): -It is the greatest demand of load on the power station during a given period.I.e. The maximum of all the demands that have occurred during a given period (may be a day, may be an hour etc.).Need of maximum demand in Electricity bill?When the rate of electrical energy is charged on the basis of maximum demand of the consumer & the units consumed, it is called two-part tariff.In this total charge is divided into two.A) Fixed charge à depends on maximum demand of consumerB) Running charge à depends on no. of units consumedIt is measuring by installing maximum demand meter. Charges are made on the basis of maximum demand in kVA & not in kWMaximum demand used to be measured by a demand needle on the meter, that would actually store only a peak demand. When you start an electric motor, this peak can be very high for a second or two. For this reason, more modern meters calculate an average demand over some period of time (often 15 minutes), and the maximum of those average demands is used as the maximum demand for billing purposes.Billing by maximum demand allows the utility to bill for the cost of installing better wiring and transformers for customers with a large active demand (KW).Values other than KW can be measured the same way for other demand values.
Maximum demand is usually observed and not measured, depending upon which discipline is involved.==Maximum demand is measured using a thermal demand indicator, which is installed at the substation.
Demand Forecasting Is the estimation of total and maximum quantity needed by the consumers in the market at future time. It must not be higher or lower than the balanced demand. TYPES; qualitative and quantitative demand forecasting.
sir, i want to know about maximum demand controller, to control electricity maximum demand is required for industries to avoid any penalty, thanks.
Diversity describes the situation in an electrical installation in which (1) not all loads connected to the system are operating simultaneously, or (2) loads are not simultaneously operating at the maximum rating. Diversity is used when determining the current loading on an electrical system in order to determine appropriate conductor sizes.Allowable diversities are usually specified in the relevant electrical code or wiring regulations. For example, the 'On-Site Guide' supplement to the UK's BS 7671:2008 Wiring Regulations specifies how demand is to be determined for a household cooking appliance (range) as follows:"The first 10 A of the rated current, plus 30% of the remainder of the rated current, plus 5 A if a socket outlet is incorporated in the control unit."
