The Metrohm HVI-F0357A High Voltage Indicator can be used to verify the presence of a voltage in high-voltage equipment such as busbars and within switchgear enclosures.
Once proved using the supplied proving unit, the Metrohm HVI-F0357A High Voltage Indicator can be applied to an HV source. If a voltage is detected the indicator will alert the user via flashing neon lights; the flashing of these lights will becoming increasingly rapid as the level of voltage detected increases, until reaching a steady state at 6.35kV (the phase to earth voltage on 11kV systems).
This Metrohm HVI-F0357A High Voltage Indicator can identify voltages as low as 200V to as high as 15kV AC/DC. It is suitable for checking DC systems and features a high-immunity to interference fields. Furthermore, the Metrohm HVI-F0357A High Voltage Indicator utilises a proven resistor chain method of measurement.
The Metrohm HVI-F0357A High Voltage Indicator is ideal for ensuring the safety of maintenance and installation personnel. To this end, it features clearly marked safety limits, as well as a handguard with a viewing window.
Finally, the Metrohm HVI-F0357A High Voltage Indicator is compact in size making it suitable for use in tight spaces and has been optimised for use both inside and outside (in dry conditions). It is therefore ideal for ensuring that high-voltage apparatus is earthed safely.
