SG3005 -
Shanghai Jiuzhi Electric Co., Ltd.
The instrument can measure DC positive and negative value of DC voltage, ripple voltage, ripple factor. It can measure AC sine wave (power frequency) and the AC of non-sinusoidal wave voltage peak (positive peak value, negative peak value, peak-peak value), peak value/ √ 2 (true RMS), RMS value of waveform deviation factor and higher harmonics. And can display and save the voltage waveform, pressure raising curve.

SG9101 -
Shanghai Jiuzhi Electric Co., Ltd.
Interference Distinguishing Partial Discharge (PD) Detector is a new type apparatus developed by the institute after SG-8001 (modeled from Model-5), SG-8201 and SG-8601 PD apparatuses. Basically it keeps the merits and functions of the above three types apparatuses. SG9101 adopts special interference distinguishing logical circuit, which can discriminates the accidental interference. (The interference must be high than a set threshold and last 4 test periods at least, the “effect” will be shown). Cooperating with the time window, it can enhance the ability to discriminate and eliminate external interference.

SG3004-12(14) -
Shanghai Jiuzhi Electric Co., Ltd.
High voltage impulse test is used to assess the quality of any high voltage equipment. The test object is subjected to a fast voltage impulse of defined wave shape caused by the test object are used for detection of insulation strengths and/or faults. It is commonly used for routine testing of transformer, bushings or other high voltage equipment.

YDSW Series -
Shanghai Jiuzhi Electric Co., Ltd.
SF6 insulated Test Transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and in the field, and for testing the other substation equipment. It is also the portable and easy maintenance solution. The SF6 test transformers can be flanged directly to the GIS for testing which make the partial discharge test easy and quick. These systems are particularly suited for on-site tests of GIS after installation. In the factory, they are used to test sub-assemblies and components directly in the manufacturing line.

SGM Series -
Shanghai Jiuzhi Electric Co., Ltd.
Resonant Test Systems, type SGM is applied for the generation of a continuously variable alternating (AC) voltage of a fixed frequency (mainly 50 or 60 Hz) for high-voltage (HV) routine, type and development testing of capacitive test objects. They can also be applied for HV on-site tests, but SAMGOR offers for that application the more economic solution of frequency-tuned resonant test systems.

SGFS -
Shanghai Jiuzhi Electric Co., Ltd.
The multiple chopping gap is used to chop lightning impulses on the front and/or on the tail.The multiple chopping gap serves simultaneously as a load capacitor for the impulse generator and allows excellent reproducibility of the chopping time and does not distort the wave shape until the chopping point.The sphere distance is automatically adjusted and operated by the controls of SG2010 and SG2011. A manual control box is available as well.
-
RZF Series -
Shanghai Jiuzhi Electric Co., Ltd.
Resistive voltage dividers have very good response parameters. Therefore they are used for measurements for full and front chopped lightning impulses or impulses voltages with steep wave fronts, also in the special condition it can be used for measuring DC.
