IEC Measurement Categories

Definitions and Examples:

1. No Measurement Category not in CAT II, III or IV
   Definition: Many types of test and measuring circuits are not intended not in CAT II, III or IV to be directly connected to the mains supply. Some of these measuring circuits are intended for very low energy applications, but others of these measuring circuits may experience very high amounts of available energy because of high short-circuit currents or high open-circuit voltages. There are no standard transient levels defined for these circuits. An analysis of the WORKING VOLTAGES, loop impedances, temporary overvoltages, and transient overvoltages in these circuits is necessary to determine the insulation requirements and short-circuit current requirements.
   Examples: Thermocouple measuring circuits, high-frequency measuring circuits, automotive testers, and testers used to characterize the mains instal-lation before the installation is connected to the mains supply.

2. Measurement Category II CAT II
   Definition: MEASUREMENT CATEGORY II is applicable to test and measuring circuits connected directly to utilization points (socket outlets and sim-ilar points) of the low-voltage mains installation.
   Examples: Measurements on MAINS CIRCUITS of household appliances, por- table tools and similar equipment, and on the consumer side only of socket- outlets in the fixed installation.

3. Measurement Category III CAT III
   Definition: MEASUREMENT CATEGORY III is applicable to test and measuring circuits connected to the distribution part of the building’s low-voltage mains installation. To avoid risks caused by the HAZARDS arising from these higher short-circuit currents, additional insulation and oth-er provisions are required.
   Examples: Measurements on distribution boards (including secondary meters), photovoltaic panels, circuitbreakers, wiring, including cables, bus- bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment such as stationary motors with permanent connection to the fixed installation.

4. Measurement Category IV CAT IV
   Definition: MEASUREMENT CATEGORY IV is applicable to test and measuring circuits connected at the source of the building’s low-voltage mains installation. Due to these high short-circuit currents which can be followed by a high energy level, measurements made within these lo-cations are extremely dangerous. Great precautions shall be made to avoid any chance of a short circuit.
   Examples: Measurements on devices installed before the main fuse or circuit breaker in the building installation.

Definitions and Examples:

Overview of measurement categories according to IEC 61010-031
O = No Measurement Category (Other circuits that are not directly connected to mains)

• Pollution Degree 1
  No POLLUTION or only dry, non conductive POLLUTION.
  NOTE: The POLLUTION has no influence.

• Pollution Degree 2
  Only- non conductive POLLUTION. Occasionally, however, a tempo-rary conductivity caused by condensation must be accepted.

• Pollution Degree 3
  Conductive POLLUTION occurs or dry, non-conductive POLLUTION occurs which becomes conductive due to condensation which is to be expected.

Safety Information

• To avoid personal injury and to prevent fire or damage to this product or products connected to it, review and comply with the following safety precautions. Be aware that if you use this probe assembly in a manner not specified the protection this product provides may be impaired. Only qualified personnel should use this probe assembly.

• Use only grounded instruments.

• Do not connect the probe ground lead to a potential other than earth ground. Always make sure the probe and the measurement instrument are grounded properly.

• Connect and disconnect properly.

• Connect the signal connector of the probe to the measuring device and connect the pow-er supply to the probe to make sure that there is a continuous ground connection from the measuring  device to the probe. Then connect the two probe inputs to the voltage-free measuring point of your DUT. Remove the probe inputs only in an de-energized state before disconnecting the power  supply. Then disconnect the power supply, and finally remove the signal connection to the measuring device.

• Beware of High Voltages.
  Observe probe and probe accessory ratings. Do not apply any electrical potential to the probe input which exceeds the maximum ratings of the probe or the accessories connected to it. In a combination always the lower rating / measurement category applies to both probe and accessories connected to it. Make sure to comply with the voltage versus frequency derating curve.

• Keep away from hazardous live circuits.

• Avoid open circuitry. Do not touch connections or components when power is present.

• Avoid unnecessary stress.

• The small electrical components of the probe are sensitive to shock and impact. Avoid any unnecessary kinetic stress to the probe like throwing, falling and strong vibrations.

• Use only original accessories and power supply.

• The accessories provided with the probe have been safety tested.

• Do not use any other accessories and power supply than those “originally” provided.

• Keep products clean and dry.

• Remove all connections of the probe before cleaning.

• Do not operate with suspected failures.

• Refer to qualified service personnel.

• Do not operate in wet or damp conditions.

• Condensation may occur if a unit is moved from a cold to a warm environment.

• Do not operate the product in an explosive atmosphere.

Note that the max. input voltage rating of the probe decreases as the frequency of the applied Sine signal increases (see Voltage Derating on page 26).
See the relevant section of this manual for further information on maximum input voltage, voltage derating and definitions of relevant IEC Measurement Categories (CAT).

About BumbleBee®
The PMK BumbleBee® high voltage differential probe series offers industry leading performance up to 500MHz bandwidth for today‘s power device design challenges, especially those using wide bandgap devices, such as SiC and GaN. The ±2000V, ±1000V, ±400V and ±200V differential and common-mode input voltage ranges makes BumbleBee® probes an ideal choice for designing and evaluating power circuits, such as switching power supplies, motor drives, inverter, IGBT circuits and frequency converters in the different voltage classes. BumbleBee® series probes have four adjustable input attenuation ranges allowing the user to select the voltage range needed to achieve the lowest noise and best possible resolution. The probe is compatible with any oscilloscope with a 50Ω input impedance and has a user adjustable DC output offset correction range of ±4V (output referred).

All BumbleBee® series probes can be controlled from the controls located on the probe head or via remote control. The „PMK Probe Control“ software provides the ability for the user to control the probe remotely via a computer, and provides the user with a graphical user interface. The software is free of charge, and included with PMK’s 2ch and 4ch power supplies PS-02 and PS-03, which are required to power the probe. The PS-02 and PS-03 power supplies all have a USB interface and are available with optional LAN interface. The 1 channel battery pack power supply AP-01 provides >8h of portable and isolated operation, which allows the user the flexibility of where the probe can be used. The AP-01 supplies power only to the probe with no software remote control.
ISO17025 calibration upon delivery or as re-calibration is available.

Measurement Principle
The high voltage differential probe consists of two balanced precision attenuators, which are differentially matched. The attenuators scale the input voltage before passing into the differential amplifier. The output of the differential is fed over a driver stage to the 50 Ω input of a measuring device.
