Product introduction:
The low frequency pulse square wave injection method can reliably and accurately monitor the insulation resistance of AC, DC and AC/DC hybrid IT system (ungrounded system) to ground. Due to various applications, system types, operating conditions, applications of variable speed drives, high system leakage capacitance, etc., the measurement technology must be able to meet different requirements to ensure optimal response time and relative uncertainty. Different measurement conditions that can be selected from the setting menu allow the optimization and adaptation of measurement technology for special applications
