1. DESCRIPTION OF EQUIPMENT
The KV series of high voltage test systems consist of a separate control unit and high voltage
transformer. In addition, low partial discharge systems (-LD suffix on unit name) have a brush
noise filter which is fitted in the power lead between the control unit and HV transformer.
Units with test timer option (-T suffix on unit name) have a test timer fitted that sounds an
alarm at the end of the preset test period.
The mk2 versions of the KV series have safety systems incorporating the following features:
Emergency stop button on control unit
Dual output contactors controlled by safety monitoring relay
Audible alarm on detection of contactor fault
Safety monitored external dual channel emergency stop/interlock circuit
Output for external signal beacons
Output for control of automatic earthing mechanism
All references to the “KV series” in this manual refer to the KV30-100 mk2, KV50-100 mk2,
KV50-200 mk2 and KV100-100 mk2 and low discharge derivatives unless a specific reference
is made to a particular unit.
NOTE
– To operate this equipment it will first be necessary to connect to an external
interlock circuit using the 6 pin plug provided. See section 1.7.2 for further information.
