MEASURING (OVERVOLTAGE) CATEGORIES DEFINITIONS

The norm EN 61010-1: Safety requirements for electrical equipment for measurement, control and laboratory use, Part 1: General requirements, defines what measuring category, usually called overvoltage category, is. On § 6.7.4: Measuring circuits, it says: (OMISSIS) circuits are divided into the following measurement categories:

• Measurement category IV is for measurements performed at the source of the low-voltage installation.
  Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.

• Measurement category III is for measurements performed in the building installation. Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to fixed installation.

• Measurement category II is for measurements performed on circuits directly connected to the low voltage installation..
  Examples are measurements on household appliances, portable tools and similar equipment..

• Measurement category I is for measurements performed on circuits not directly connected to MAINS.
  Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that reason, the norm requires that the transient withstand capability of the equipment is made known to the user.

GENERAL DESCRIPTION

The meter can perform the herewith measurements:

• DC and AC TRMS Voltage up to 1000V
• DC and AC TRMS Current up to 600A
• Resistance and continuity test with buzzer
• Capacitance
• Frequency with test lead and jaws
• Duty cycle
• Diode test
• Temperature with type K probe
• AC voltage detection with and without contact with integrated sensor

Each parameter can be selected by rotating the 7 positions switch. To facilitate the hold function the HOLD key is available. There are also the following keys: “MODE “MAX/MIN”, “Hz%“, “PK/REL” and “ ”. For their use please see § 4.2. The selected quantity appears on a LCD display with indication of measurement units and functions. An analogical barograph it is also available

TRMS AND MEAN VALUE MEASURING INSTRUMENTS

Safety testers for alternate parameters are divided into two big families:

• MEAN VALUE instruments: instruments which measure only the value of the wave at the fundamental frequency (50 or 60 Hz)
• TRUE ROOT MEAN SQUARE instruments, also defined as TRMS: instruments which measure the true root mean square value of the quantity under test.

In presence of a perfectly sinusoidal wave, both families provide identical results. In presence of distorted waves the readings are different. Mean value instruments provide only the value of the fundamental wave while True RMS instruments provide the value of the entire wave, including harmonics (within the passband of the instrument). Accordingly, if the same quantity is measured with both kinds of instruments, the measured values are identical only if the wave is purely sinusoidal. Should it be distorted, True RMS instruments provide higher values than medium value instruments.

TRUE ROOT MEAN SQUARE VALUE AND CREST FACTOR DEFINITIONS

The current effective value is defined as follows: “In an interval of time equivalent to a period, an alternate current with effective value having an intensity of 1A, by passing on a resistor, disperses the same energy which would be dispersed in the same period of time by a direct current having an intensity of 1A”. From this definition comes the numerical expression: G= ∫ The effective value is indicated as RMS (root mean square). The Crest Factor is defined as the ratio between the Peak Value of a signal and its
effective value: CF (G)=  This value varies according to the waveform of the signal, for a purely sinusoidal wave it’s worth 2 =1.41. In presence of distortions the Crest Factor assumes higher values as long as the wave distortion is higher.
