High Voltage Isolation Meter METRISO 5000 A
Analogue high voltage isolation meter run with batteries / for test voltage up to 5000 V and a measuring range up to 1 TOhm / to check isolation resistance at lines, prefabricated parts, construction material, compounds / analogue display

This analogue high voltage isolation meter is equipped with adjustable high voltages of 100 V, 250 V, 500 V, 1000V (according to EN 61 557 part 1) and 1500 V, 2000 V, 2500 V, 5000 V. This isolation meter is a standard isolation resistant measuring device or as a detector for breakdown at electric lines (on machines, transformers, cables as well as electric facilities, e.g. locomotives, trams, vessels). The high voltage isolation meter can also be used to check isolator panels, compound material and synthetic panels on isolation resistance for respective electric conductivity of different construction materials. The maximum isolation meter can be read at the analogue display. By means of voltage measuring ranges the zero potential of test objects in networks up to 2 kV can be determined. This is important in terms of isolation resistance detection since external voltages falsify the measuring data. Capacitive test objects, e.g. cables and windings that can be charged on the test voltage, will discharge due to this high voltage isolation meter. Therefore the descent of the voltage can directly be monitored due to needle deflection at the meter. The highly isolated measuring lines are plumbed for safety- and measuring- related causes. Thus an endangerment by accidental pulling the cable, e.g. during recharge through capacitive test objects, can be avoided.

General characteristics

Information about initial and repeat test on power current installations up to 1000 V

- Isolation measuring is performed in a voltage free state.

- Isolation measurement only takes place in ranges that lie in-between the measuring voltage, so
  either switch everything on and measure before and after the switches or bridge all open contacts
  before measurement and measure from feeding.

- If the measuring-circuit contains a capacitive consumer load, discharge after measurement.

- You decide on-site which measuring method to choose. Short-circuit L+N is often more complex
  than separate measurements. Those allow conclusions about isolation of the sole lines and thus
  allow comparisons. Furthermore the isolated measurement of the single lines against PE or
  between one another is an effective method of preventive fire protection. RCDs cannot recognize
  isolation errors between the active lines.

- In case of retest always measure L+N against PE (protection of electronic operation equipment).
  Single pole operation devices are to be tested in TN-S/TT/IT systems then, without switching them
  on.

- In case of TN- systems open N-PE-bridge, in TT-system disconnect neutral conductor.

- In case of measurements of installations with overvoltage arrester (varistor base demand- class B or
  C) those are to isolate earth-face whilst isolation measurement. In case of device protection, e.g.
  socket (requirement class D) - this procedure is not necessary. 

- Measuring voltage of 250 V is permitted

- Common values: - at initial test without connected operation medium > 100 MΩ (see therefore as
                             well DIN VDE 0100 part 610)
                           - In case of repeating tests with connected operation devices ~ 300 kΩ.
