Test & Measuring Instruments-> High Voltage Measuring System

[1]   Click to Enlarge AC & DC HIGH VOLTAGE MEASURING KIT Apart from High Voltage Sphere Gap and High Voltage PT operated voltmeter we can also manufacture- High Voltage Potential Divider This can be either resistive or capacitor type potential divider. Lower arm to higher arm ratio is generally 1:100 or 1: 1000 depending on the voltage to be measured. We manufacture potential divider for both AC & DC voltage. Max. Range of DC voltage is 300KV and AC 200KV. Peak Voltmeter This is basically a High Voltage voltmeter comprising of a High Voltage Potential Divider with a readout which will indicate the peak value of the voltage to be measured. This is particularly useful when the voltage to be measured is neither a DC nor a regular sinusoidal voltage. Max. Range of peak voltmeter manufactured by us is 300KV. See Enlarge Click to Enlarge PT OPERATED HIGH VOLTAGE AC MEASURING SET This set is suitable to calibrate High voltage measurements. It consists of - i. High Voltage PT ii. Measurement unit High Voltage PT One end of PT winding is grounded. Max. Measurement Voltage: Depending on PT, spread over different range upto 100KV i.e. 10KV, 40KV & 100KV. Secondary Voltage: Depends on Primary High Voltage but restricted to 1000V. Measurement unit: Digital voltmeter. Accuracy of measurement: + 1%. Interconnecting cable between the PT secondary and voltmeter is of at least 3 meters length. See Enlarge Click to Enlarge Sphere gap assembly for high voltage measurement & other applications Sphere gap assemblies are designed and fabricated as per IS 1876 / 1961, which lays all constructional details and limitations for the unit. This method is however a recognised one for measuring high voltage in DC or AC or Impulse type voltage. construction Two spheres of equal shape and size are made from brass or copper sheets, polished to have mirror finish. The distance adjustment is manual or motorised depending upon the size and choice of customer. For manual adjustments, the vernier-scaled dial is provided to have better accuracy and resolution for setting required gaps. For motorised unit, the gaps are set by motor and the indication is determined on large circular indicator. For obtaining constant repeatable results an irradiation source can also be supplied if required by the customer.
