Testermeter- SKIM800 Insulation Monitor low-frequency pulse square wave injection
| SKIM800 insulation monitoring instrument adopts the principle of low-frequency pulse square wave injection to accurately monitor the insulation resistance of AC, DC, and AC/DC hybrid IT systems (unearthed systems) below 1KV. Collaborating with IEX3000 coupler for online monitoring of 1KV~10KV power grid, SKIM800 can be used for main circuits and control circuits. |
