Impulse Current Generator by wide range of with wide range

【CDLD series】

The CDLD impulse current generator is featured by wide range of applicable wave forms. It is mainly used to test the residual voltage and motion load of valve discs, unit modules and SPDs. It is also used for routine test of HV apparatus manufacturers.

Main features:

Product	D type impulse current generator
Type	CDLD
Structure	D type	Each unit consists of 2-4 horizontal large capacitors laid on the frame, a multi-tap inductor is vertically installed above the sphere gap; 2-6 units are laid around the sphere gap in D pattern; inductors can be adjusted according to wave form and test object resistive during tests
Functions	It is mainly used to test the residual voltage and motion load of valve disc, arrestor and SPDs.
Advantages	Good appearance	As shown in the photo
Module design	The charging unit, resistors, capacitor frame, sphere gap are separate functional modules for easy reconfiguration and repair.
Flexible combination	Flexible combination of different units and within the units enables generating wave forms of different energy.
Easy modulation	Flexible combination of inductors and capacitors for easy modulation
Compact design	Spark gap cylinder, test bay, measuring components are assembled on a base frame; compact design and low inductance
Stable and reliable triggering	Durable graphite spark gaps; gap distance is adjusted by a drive motor; impulse firing available with stable triggering
Mobility	Universal wheels on each module for easy displacement
Stable performance	Long-time operation at a voltage lower than 80% of rated voltage
Performance	Current impulse	4/10μS
8/20μS
30/80μS
10/350μS
1000/2000μS
The impulse current generator and the charging unit are separate.
Charging unit with dual voltagerectification
Charging unit with automatic grounding and polarity reversal (external)
Encapsulated spark gaps with less noise
Capacitor with grounding device
Rogwoski circuits and dividers
Leading technologies and performance
