RE, Sphere Gap is provided with Motorised arrangement to adjust the gap. The lower sphere gap shall Motorised and shall move upwards and downwards for the adjustment of gap. The upper sphere shall be hang shall be roof of the test lab with in insulator and current limiting resistance shall be provided.
Description
Kilo Volt Meter (kV) meters used tomeasure the kilo volt value of an Instrument Transformer, CT/PT etc. The unit is used for higher value calibration with a wide range from 1% to 110%. Kilo Voltmeters are highly accurate, portable voltage measurement systems traceable to NABL standards. The Kilo meter series consists of a high voltage divider assembly, a precision readout device and interconnection leads. The battery operation makes the system completely portable for field testing while the precision divider assembly and readout device makes it suitable for laboratory use.
Description
Induced Over Voltage Test Set (DVDF) is used for testing the strength of insulation between turns and between other points of the transformers etc. as stipulated by BIS or other standard specification. For this test Double Voltage is applied across L.T. terminals for one minute, and to limit the magnetizing current over frequency is utilized.
It is a mechanically coupled unit having motor and Generator with power and control panel to regulate the output voltage.
A suitable control panel is utilized for motor starting, generator output control, measurement of all three phases, voltage and current for input and output with protection circuit.
